Attention Commercial Grower—Vital Information:

Do the Salts You Use For Your Cannabis “Hit the Shift” Between the Grow and Bloom Phase?

Because if they’re not…

You’re almost certainly sacrificing cannabinoids, yields, and your stake in the marketplace.

In fact, commercial growers who are trying to save money on the front end by mixing their own salts are actually LOSING money.

And they’re just as bad off if they’re buying their nutrients from new startups or ag companies pretending to sell “cannabis” fertilizer.

You see, of all the cannabis fertilizer companies, only one has done the research to discover (and leverage) the dramatic shift in the macro, secondary, and micronutrients that cannabis needs between the grow and bloom phase.

The reality is, unless a nutrient company has done the research on the cannabis genus — and what it really takes to unlock the full potential of your crop — they don’t understand how critical it is to get this right.

And make no mistake…

If you want to harvest an extra half-pound or even pound more bud per light…

With significantly higher cannabinoids…

You MUST Hit the Shift.

Let me explain…

Advanced Nutrients has made over 53 breakthroughs that revolutionized the way cannabis is cultivated.

However…

The Most Important Discovery of All…

… the one that’s had the greatest impact on yields, cannabinoid production, and grower reputations …

… is one that the fertilizer companies (who claim their products are for cannabis) remain completely in the dark about.

And one look at their labels proves their products are NOT designed to produce heavy yields of high-cannabinoid cannabis — the evidence is right there in black and white. Actually, it’s what ISN’T there that matters most.

This groundbreaking discovery is Hitting the Shift.

Here’s How the University of Mississippi and Dr. Mahmoud Elsohly Discovered Firsthand the POWER of Hitting the Shift…

The University of Mississippi is the only university in the United States with a license to conduct cannabis research.

The school’s team of agronomists developed a cannabis fertilizer (formulated with their most leading edge research) and wanted to test it against the cannabis nutrients with the best reputation for results among growers.

So they got in contact with Advanced Nutrients and ran their fertilizers against ours. The study was conducted by Dr. Mahmoud ElSohly, one of the world’s foremost researchers and authorities on cannabis.

Here are the results …

Results of Study Performed From Dr. Elsohly at University of Mississippi

(A)

(B)

(C)

Dr. Elsohly was BLOWN AWAY. As you can see in Figure C …

Advanced Nutrients Increased Useable Biomass by 21%, THC by 42.05%, and CBD by 55.8%

THAT’s the power of Hitting the Shift.

And keep in mind, this study was done in 2003, back when Advanced Nutrients was on only our 3rd generation of fertilizers. We’re currently on our 8th generation.

Now, unlike when I began experimenting on cannabis back in 1983 …

Most Serious Growers Today Understand That…

  1. Feeding cannabis the nutrients it needs to thrive is essential to maximize yield, cannabinoid production, flavor, and aroma.
  2. Cannabis has different requirements during the grow and bloom phases.

Hoping to capitalize on the cannabis gold rush, fertilizer companies are racing into the industry, scrambling to do a cash grab and making all kinds of wild claims about their products being for cannabis…

… when what they’re really selling is regular old ag fertilizer, much more suited to tomatoes or zucchini than your plants.

They advertise that their nutrients are designed to meet cannabis’s unique needs. However…

Here’s What These Fertilizer Companies Don’t Know About Cannabis

The difference in cannabis’s requirements between the grow and bloom phases is FAR greater than these companies understand. In fact, the Shift is MASSIVE.

The data shows that during the Grow Phase, cannabis uses MORE calcium, iron, manganese, and boron and LESS nitrogen, potassium, zinc and phosphorus.

And in the all-important, money-making Bloom Phase, cannabis devours MORE nitrogen, potassium, and zinc (and a tad more phosphorus) and uses LESS calcium, iron, manganese, and boron.

Just look at the following data in Figure D. from BC Research, the research arm of University of British Columbia…

Here’s What Hitting the Shift Is All About

(D)

That’s the Shift. And “Hitting the Shift” means fulfilling all these phase-dependent nutritional needs so your cannabis can reach the absolute peak of its true genetic potential.

For example, let’s take THC. If the genetic potential (or genetic limit) of your crop is 37% THC, the ONLY way to reach that potential (and produce flowers with 37% THC) is to Hit the Shift. Otherwise, it simply isn’t possible.

And your crop has a true genetic potential for all cannabinoids, as well as terpenes (responsible for flavor and aroma) and yield.

Wouldn’t it be nice to harvest an extra half-pound or even pound or more of bud per light, of significantly higher THC/CBD cannabis, by making one simple adjustment to your grow?

Well, it’s actually a series of adjustments, but the right nutrients can do all the work for you.

Your role is easy…

To Reach the True Genetic Potential of Your Cannabis and Maximize the Value of Your Crop…

… Simply check any dry fertilizer label and confirm the nutrient ratios are dialed in to Hit the Shift, then use as directed.

Once you do that — providing you’re using quality genetics — THAT’s when you’re talking yields of 2-4 pounds per light and THC levels well north of 30%. Now…

Here’s How to Compare Dry Fertilizer Labels…

Let’s look at the labels of two water-soluble powders…

  • Advanced Nutrients’ Sensi Grow and Bloom Professional Series
  • Athena’s Core Three Part Nutrient Mix – Grow, Core & Bloom

First off, notice that Athena uses a three part system, consisting of Grow, Core, and Bloom products, with ALL of their micronutrients in one product—Core.

Advanced Nutrients Sensi Grow and Bloom Professional Series, on the other hand, is a four part system, with a Part A and a Part B for both the Grow and Bloom.

This Distinction is CRUCIAL…

… because it’s Part A and Part B that enables your Advanced Nutrients system to Hit the Shift.

When a fertilizer company puts all its micronutrients into one product, (as with Athena’s Core), it CANNOT Hit the Shift and bring cannabis anywhere near its true genetic potential.

Hitting the Shift is an absolute MUST if you want to get the most from your crop. Otherwise, your yields, potency, and — ultimately — reputation will suffer.

(BTW, in just a bit, I’ll name every four part system on the market that Hits the Shift.)

Now, Let’s Look at Copper…

In Figures E and F you can see that Advanced Nutrients Sensi Grow and Bloom Professional Series contains 0.002% copper and Athena’s Core Three Part Nutrient Mix has 0.01% copper.

Unfortunately for growers, Athena’s product locks you into the dreaded Copper Trap. Now…

Here’s What You Need Know About the Copper Trap

As you’re aware, copper plays a key role in photosynthesis.

However, to achieve photosynthesis, cannabis actually requires very little copper.

Give your crop even a tad more than it needs and…

Copper Can Quickly Become TOXIC and Do Irreparable Damage to Your Crop’s Health, Yield, and Value

Many growers have had to learn this the hard way.

Take, for example, a well-known cannabis company (that I won’t name) listed on the Canadian Securities Exchange.

Crop after crop, their yields were DISMAL. They struggled to even keep their plants alive!

These highly-experienced growers couldn’t figure out just what the heck was going on. They were certain they were doing everything right. But no matter what they tried, their plant health, cannabinoid production, and yields were AWFUL.

Testing revealed the plants were suffering from copper toxicity. The growers were dumbfounded. Afterall, they’d been using their dry fertilizer as directed.

Then, after painstakingly deconstructing their grow…

They FINALLY Located the Source of Toxicity…

When they’d built the grow, they made the mistake of running copper piping instead of PVC for their main feed line.

Despite the fact that this piping was less than a hundred feet in length, its impact on their crops was catastrophic and cost them an incredible amount of time and money.

The point is, while a little bit of copper is necessary for your crops, even a trace amount of excess copper can become toxic and negatively impact crop health, cannabinoid production, and yield.

Don’t Let Copper Toxicity DESTROY Your Chances of a Heavy Harvest

Now, let’s compare the copper in Advanced Nutrients’ Sensi Grow and Bloom and Athena’s Core Three Part Nutrient Mix.

As you can see in Figures E, Advanced Nutrients’ Sensi Grow and Bloom has .002% of copper, which is the optimal amount of copper for your crop to thrive while safely avoiding toxicity.

Athena’s product, on the other hand, contains 0.01% copper. If you were to use as directed, you’d end up giving your crops 400% more than what they need. Ouch!

That’s WAY Too Much Copper!

That much copper can quickly become toxic and damage your crop.

However, if you tried to prevent copper toxicity by cutting back on Athena’s Core, your crops could easily become deficient in many of the other important micronutrients cannabis requires.

So either way, you lose. That’s the Copper Trap!

And it’s just one of the many reasons you want to avoid these cheap ag fertilizers that claim to be for cannabis.

Saving a few bucks on the front end simply is NOT worth getting caught in the Copper Trap.

Nor is it worth missing your opportunity to Hit the Shift.

Next, Let’s Look at Iron…

Iron is essential for photosynthesis. And cannabis uses significantly more of it than most agricultural crops.

During the grow phase, iron plays a vital role in nitrogen uptake.

Then during the bloom phase, cannabis requires much less of it.

Which is why, as you can see in Figure E, Advanced Nutrients’ Sensi Grow and Bloom contains less iron in our Bloom than in our Grow.

While Athena’s Three Part Nutrient Mix contains the same amount of iron for both phases. This is a problem because too much iron can interfere with the uptake of several key nutrients, ESPECIALLY potassium, which your crop wants to DEVOUR during the bloom phase so it can produce those heavy yields of high-cannabinoid buds you want.

And not only does Athena’s product fail to Hit the iron Shift between phases, but…

An Even Bigger Problem With Athena’s Iron Is That…

… they use only two chelates — EDTA and DTPA — which can easily lead to extremely poor absorption.

And when your cannabis can’t absorb iron properly, you impede your plants metabolism and can end up with pH issues and unhealthy plants whose genetic potential will never see the light of day.

Advanced Nutrients’ Sensi Grow and Bloom, on the other hand, contains three forms of chelated iron — EDTA, EDDHA, and DTPA — providing for a greater range of pH and much higher absorption.

The chelation process is essential to healthy, robust crop growth — but it requires precision pH balances in your nutrient solution.

Now, cannabis is an acid-loving plant that performs best at a pH of 5.5-6.3.

An acidic rhizosphere (or root zone) creates larger, more productive roots, with increased nutrient availability and ideal conditions for cannabis plant growth.

In fact, 217 studies show that bigger roots produce bigger yields.

So it’s essential that you provide an acidic rhizosphere for your plants.

And here’s…

The Secret to Transforming Your Root Zone Into a pH-Down Machine So You Can Keep Your Cannabis in the pH Sweet Spot (And Enjoy the Largest Yields of the Sweetest, Stickiest, Most Potent Buds Possible)

Among your most powerful tools to maintain an acidic root zone are cations (positively charged ions).

Cations cause your cannabis to exude an acidic substance, making your rhizosphere acidic.

So cations DECREASE the pH of your growing medium and help…

Keep Your pH in the Sweet Spot Your Cannabis Needs to Reach Its True Genetic Potential

Now, most products touted as “cannabis fertilizers” are not only devoid of cations…

… but are also loaded with anions (negatively charged ions), which cause your roots to release an alkaline substance and will force your pH out of the sweet spot your cannabis needs to thrive.

Products rich in anions as opposed to cations simply are NOT designed for cannabis.

If heavy yields are what you’re after, it is CRITICAL that your fertilizer is cation-rich.

And as you can see in Figures E-H, Advanced Nutrients Sensi Grow and Bloom is rich in cations, like urea — which cannabis LOVES — to acidify your growing medium.

Athena’s product — as with most fertilizers advertised for cannabis — is NOT cation-rich and does NOT contain urea.

What About Calcium?

Just like a growing child requires more calcium than an adult, so does your cannabis (refer to Figure G.)

And just like consuming too much calcium as an adult can lead to a host of nasty health problems, giving your crops too much calcium in the bloom phase can lead to calcium toxicity.

Now, as you can see in Figure G, to ensure you Hit the calcium Shift (and avoid the troubles that come from overfeeding calcium), Advanced Nutrients contains less calcium in our Bloom than our Grow.

While Athena’s Three Part Nutrient Mix does NOT Hit the calcium Shift.

In fact…

It’s the Same with Boron, Potassium, Zinc, Phosphorus, and Manganese — Athena Fails to Hit the Shift in EVERY Area

Every area but one, actually. Yep…

Athena got ONE thing right — the nitrogen Shift.

However, like so many other companies that advertise that their regular old ag fertilizers are for cannabis, Athena dropped the ball in ALL these other vital areas…

How Advanced Nutrients Turns Your Cannabis Plants Root System Into Acidic pH Producing Machines

The bottom line is…

Athena’s Three Part Nutrient Mix Is NOT a Good Choice for Your Cannabis

Not even close.

Now, it is better than giving your crops nothing. And it’s a little better than using Miracle-Gro. But it simply does NOT contain what your cannabis needs to express its true genetic potential.

However, here’s the thing…

Athena’s Three Part Nutrient Mix isn’t the only flawed three part system on the market. In fact…

ALL Three Part Nutrient Systems Are FLAWED

That’s right. ALL three part systems are flawed because they don’t Hit the Shift that occurs between grow and bloom phases.

But, hold on a sec … doesn’t Advanced Nutrients make a three part liquid system?

Yep. It’s called Jungle Juice Grow, Micro, Bloom. And while it’s proven itself to be hands down the best three part system on the market, it doesn’t Hit the Shift and produce results anywhere near what our four part Sensi Grow and Bloom Professional Series does.

Getting the Micronutrients Right Is Essential for Maximum Cannabinoid Production and Yields

In fact, it’s the most critical part of the game. If you don’t get your micronutrients right, yields and potency WILL suffer. Period.

And when the micronutrients are all in one product — like Athena’s Core — it’s simply impossible to Hit the Shift and get the most from your crops.

Which is why Advanced Nutrients’ Sensi Grow and Bloom Professional Series contains Part A and Part B — to Hit the Shift and produce the heaviest harvest of the best damn buds possible.

It’s the ultimate easy button to increase the value of your crops. Because we’ve done ALL the work for you. Including the decades of research and the tens of millions of dollars we put into it.

All you have to do is pour. We’ve made it that brain-dead simple for you.

Now, there are other four part systems on the market. However…

ONLY Advanced Nutrients Sensi Grow and Bloom Professional Series Hits the Shift

Plenty of dry fertilizers are advertised for cannabis these days. But only Advanced Nutrients is optimized to drive cannabis to its absolute genetic potential.

The hard truth is that…

Most Companies Claiming Their Products Are for Cannabis Are Actually Just Hawking Ordinary Ag Fertilizer

Look, I understand the learning curves that companies new to the cannabis nutrient space, like Athena, are up against.

In my early years, especially back in the mid-1980s and early-1990s, I made countless mistakes with my crops. These mistakes were a necessary part of the learning process. They’re how I discovered what works and what doesn’t.

Mistakes are how we grow (no pun intended). They’re how we improve. And hopefully Athena’s Core Three Part Nutrient Mix is one Athena will learn from.

Now, beyond Hitting the Shift, there are a myriad of other benefits to using Advanced Nutrients over brands like Athena, including…

Advanced Nutrients Sensi Grow and Bloom Professional Series Is Standardized and More Concentrated Than Other Brands

One of the many reasons growers find Athena’s Three Part Nutrient Mix challenging to use is that it is NOT standardized.

Whereas Advanced Nutrients Sensi Grow and Bloom is not only 9.7% more concentrated than Athena’s product, it’s also standardized, so you’ll use equal amounts when mixing it in your feed tanks (it doesn’t get any simpler than that).

Advanced Nutrients Sensi Grow And Bloom is Made With ONLY the Highest-Quality Inputs

And we have an unparalleled reputation for purity.

Most of these companies get their elemental inputs from suppliers in China known for their lack of purity.

Advanced Nutrients, on the other hand, gets our inputs from our strategic partner Haifa, in Israel, the global leader in pure inputs for specialty plant fertilizers. And we’ve done so for the past 18 years.

The Advanced Nutrients 100% Money-Back Grower Guarantee

Check labels and you’ll find that most nutrient companies do NOT stand behind their products by offering a money-back guarantee.

At Advanced Nutrients, we guarantee you’ll be thrilled with the results our products help you achieve — and that the results will be better than with any other brand — or we’ll give you 100% your money back, no hassles or hard feelings.

What About Price?

Other than Advanced Nutrients, not a single fertilizer company in cannabis has a serious research program. Nor do they truly understand the many nuances of cannabis (like the Shift and how to Hit it).

Plain and simple, their products are NOT optimized for cannabis. So it doesn’t matter how cheap they can get away with selling their dry fertilizers. Comparing their prices with ours is like comparing a Kia with a Ferrari.

Results Matter — ROI Matters

When selecting nutrients to achieve heavy yields of high-value cannabis, the LAST thing you want to do is cut corners to save a few bucks on the front end (or your crops will suffer — every time).

What matters is getting the maximum return on investment (ROI) possible — the best damn bang for your buck you can get.

And test after test, in both laboratories and grow rooms across the globe, PROVE that Advanced Nutrients delivers hands down the best ROI in the industry. No other brand even comes close.

It’s the reason we’re behind far more Cup Wins than any other brand. It’s why not a single company would compete against us in the Million-Dollar Grow-Off Challenge, where I’d write a million-dollar check to ANY fertilizer company who could produce better crop results in a strictly controlled head-to-head grow-off (with the sole variable being nutrients).

The fact is, companies that base their products on bro science (instead of REAL science) can always afford to sell their nutrients cheap.

But, you see, when you invest in products from Advanced Nutrients…

You’re Getting 22 Years of Cannabis Research and Technology

That’s something no other brand can say.

Look, you can use ANY fertilizer to grow buds. And fertilizers like Miracle-Gro and Athena are definitely better than nothing.

But if you want to maximize cannabinoids and yields, blow the minds of your friends and other growers, and command top dollar for your cannabis, just like you must use quality genetics, you MUST Hit the Shift.

And that’s something only Advanced Nutrients can achieve.

Over time, components within the nutrients settle on the bottom of the bottle. When you pour a bottle without shaking it, you can potentially be pouring out an unbalanced solution. Shaking up the nutrient bottle ensures you are pouring the right blend into your reservoir, giving your crops the nutrition they need.

Usually, it’s not a problem. But some products are incompatible with each other and can damage your plants when they’re used together. For example, bloom boosters with high PK numbers or low-grade silica products can destabilize your nutrient mix and cause nutrient lockout.

Nutrient manufacturers design their products to be used with each other. In doing so, they include specific portions of each nutrient in each product, so crops receive the right nutrition through each stage of the grow cycle. When you stick with one manufacturer, you don’t have to worry about inadvertently destabilizing your nutrient mixture. One example of why you need to stick with only one manufacturer’s products is Advanced Nutrients’ pH Perfect line. These products are designed to keep your crops’ root zone within a specific pH range. When you use them alongside products from another manufacturer, we can’t guarantee your root zone will maintain its optimal pH level.
