Say goodbye to nutrient lockout and hello to heavier harvests. Our scientists engineered pH-Up with potassium hydroxide and pH-Down with Phosphoric Acid, so you can easily achieve the ideal pH levels for optimal nutrient absorption. We’ve developed these highly stable buffers to give you precise control over your pH, even after dilution or adjustments between reservoir changes.

  • Recalibrate pH levels with maximum buffers
  • Highly concentrated formulas for longer use


Nutrient Solutions:
Mix a new réservoir weekly.

Coco: Daily.

Other Substrates: 2-4 times/week as necessary.

Use small amounts when adjusting the nutrient solution to affect the pH level, as required. Use to maintain the optimum pH level of 5.5 to 5.8 for hydroponics and 6.2 to 6.3 for sphagnum moss and plants in containers. For best results, check the pH level daily.

pH-Up & pH-Down is specially designed for use with diverse hydroponic growing media and all continuous liquid-feed growing systems such as aeroponics, drip irrigation and emitters, NFT, flood and drain, and deep water culture.

NOTE: At Advanced Nutrients, we do not use paclobutrazol, daminozide, or any other banned plant growth regulators in our products.

pH-Up and pH-Down — Hit Your pH Sweet Spot Every Time 

Ask any grower, and they’ll tell you the same thing . . . 

You can feed your cannabis the best nutrients in the world. But if your root zone can’t absorb them, your investment goes to waste! 

Fact is . . . nutrient availability is CRITICAL to getting the lush foliage, sturdy stalks, and huge, potent buds you crave. 

And there’s one major variable affecting your garden’s ability to absorb those nutrients . . .

Your crop’s pH levels!

Because here’s the thing . . .

Your Cannabis Plants Can ONLY Absorb the Full Range of Nutrients They Need When Your pH Stays in the “Sweet Spot”

And the optimal pH range for your high-value plants is between 5.5 and 6.3. 

Now, pay close attention . . .

When your nutrient solution moves above or below this range . . . 

You MUST recalibrate your pH levels with pH adjustors. 

If you don’t monitor your pH daily and act fast to course-correct . . .

You could end up locking vital nutrition out of your garden

And without a robust range of available nutrients . . .

Your plants are left . . .

  • Slowly crawling through their crop cycle
  • Incapable of producing large, robust harvests
  • Struggling just to survive

Even worse, your plants could run out of the juice they need to produce bigger, weightier buds . . . 

Before you realize anything went wrong!

Make no mistake about it . . .

Adjusting your pH levels is critical if you want to achieve a lush, heavy harvest.

However, keep in mind. . .

Not all pH Adjusters Are Created Equal 

You see, many pH adjusters on the market don’t offer the kind of technical precision growers need to unlock hefty yields of sweet, potent flower.

And as a grower, you already know that precision is NOT a luxury . . .

It’s an absolute MUST for high-profit yields.

For starters, many of these pH adjusters feature weak concentrations . . .

Forcing you to go through bottle after bottle to keep your pH in check.

And not only do you waste product . . . AND money . . . 

You could even end up damaging your crops! 

Because here’s the thing . . .

Poorly made, unstable pH adjusters can lead to sudden pH drops or spikes. 

And instead of focusing on producing champion flower, your cannabis is forced to battle with these wild pH fluctuations instead! 

What’s more . . . they can make it difficult to achieve a precise pH level

Keeping full nutrient absorption just out of reach. 

No doubt about it. . . Monitoring pH can give even the most experienced grower a massive headache.

Unless . . . 

You Rely on PURE, Stable Concentrates to Lock in Optimal pH Levels

Imagine adding just a tiny bit of pH-Up or pH-Down to your reservoir . . . 

And basking in the immediate gratification of a perfectly balanced pH. 

Not only will you drastically reduce the number of times you need to restock on product . . .

You’ll support a harvest that remains in prime condition for maximum nutrient absorption. 

And let’s face it . . .  

After optimizing your grow room environment . . . 

Investing in the best fertilizers . . . 

And tending to your plants around the clock . . .

A stable pH is the MINIMUM you and your crop deserve. 

Needless to say, our grow experts intimately know the power of keeping your pH in its sweet spot.

And it’s why we engineered . . .

The Most Sophisticated pH Adjusters On the Market!

So you can benefit from pure, stable concentrates that automatically recalibrate your pH levels.

Now, make no mistake . . .

Arriving at these expert formulas was no easy feat. 

We knew we had to engineer adjusters that go above and beyond the standard market solution . . .

And we put rigorous quality controls in place to ensure you hit your pH sweet spot every time . . . 

From a product where a little bit goes a long way. 

The result of this commitment to excellence is Advanced Nutrients’ wildly popular pH-Up and pH-Down . . . 

A breakthrough set of adjustors for any grower who’s ready to get the optimal nutrient absorption necessary for growing lush, heavy yields

When you put our pH-Up and pH-Down to work in your garden…

  • Your cannabis plants will absorb the optimal ratios of nutrients they need to reward you with strong, sturdy plants and huge, high-value flower. 
  • You’ll stop making trip after trip to the hydro store . . . JUST to restock on weak chemical formulations 
  • And you’ll immediately achieve precise pH levels . . . withOUT harming your plants!

Imagine how great it will feel to gaze at vibrant, green harvests cycle after cycle . . .

And know all your time, money, and effort was worth it . . .

Because your crop effortlessly absorbs the nutrients you feed it. 

The bottom line is this . . .

There’s NOTHING more important for cannabis than optimal nutrient absorption. 

And there are no adjusters that are more accurate and cost-effective than Advanced Nutrients’ pH-Up and pH-Down. 

So if you want to walk away from every harvest with absolute confidence that you did everything in your power to provide your plants the nutrients needed to thrive . . .

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.

Advanced Nutrients has spent many thousands of man-hours developing a technology that automatically balances your pH for you — putting it in the “sweet spot” and holding it there for one week.

And the technology is so “smart” that it can account for many of the aforementioned variables in your grow room. Our proprietary pH buffering agents and stabilizing mechanisms became the foundation of a new system aptly called pH Perfect® Technology. Learn all about it here.
