Here’s How You Can Rest Easy Knowing Your Cannabis Crops Will Never Fail Heavy Metal Testing

Commercial growers, as you’re no doubt aware, healthy plants result in large yields of clean, potent, high-value cannabis consumers want.

And to achieve optimal crop health, consistently pass mandated testing, and realize maximum profits when you bring your cannabis to market, it’s crucial that you feed your plants only the highest quality inputs.

Because not all inputs are created equal.

To increase profit margins by minimizing costs, fertilizer companies often buy impure, bargain inputs.

Now, if you want to get the most from your cannabis and realize the greatest possible profit margins, the last thing you want to do is feed your crops low-quality inputs. Otherwise, your crops and margins will suffer. And as a lot of growers have found…

You Could Fail Cannabis Heavy Metal Testing

This is why Advanced Nutrients uses only the highest quality inputs in our fertilizers and biostimulants.

In fact, for the past 19 years and counting, we’ve gotten our inputs from our strategic partner Haifa, the global leader in pure inputs for specialty plant fertilizers.

Advanced Nutrients partners with Haifa.

We do this because clean inputs enable you to cultivate the largest yields of the safest, healthiest, most potent cannabis possible, allowing you to command the highest prices in the marketplace.

Now, let’s talk about where cannabis contamination (toxins within the plant) comes from and how it negatively impacts your plants…

Cannabis Is a Bioaccumulator Plant, Which Means It Takes in Everything From the Soil or Growing Medium – Good and Bad

It’s such an accumulator that cannabis has been used at Chernobyl to absorb radiation from the soil, decreasing radiation volume in the ground.

The fact is, everything that goes into cannabis over the different stages of its life either brings the plant further or nearer to its true genetic potential.

For better or worse, it ALL matters.

The quality and ratios of EVERYTHING in fertilizer — including macro, secondary, and micronutrients, as well as fillers — have an immense impact on cannabis’s flavor, smoothness (or harshness), potency, safety, and overall quality.

And the further you deviate from providing cannabis clean inputs in optimal nutrient ratios, the more purity, potency, flavor, yield, and consumer safety deteriorate.

And the greater your chance of failing cannabis heavy metal testing.

Now, it’s crucial to understand that…

Every Step in the Cannabis Growing Process Affects Crop Contamination Levels

And the three primary sources of contamination are:

  • Grow mediums
  • Grow room hardware
  • Fertilizer


Any of these sources can lead to heavy metal contamination and put plant and consumer health at risk.

Let’s look at copper, for example…

Copper plays a crucial role in photosynthesis, but cannabis actually requires very little of it.

Even a trace amount of excess copper can be toxic, negatively impacting crop health, yield, and cannabinoid production.

Unfortunately for growers…

Many Popular Base Nutrient Products Contain Far Too Much Copper for Cannabis, Leading To Toxicity

To make matters worse, attempting to prevent copper toxicity by reducing dosage leads to deficiencies in other essential micronutrients. This is the Copper Trap.

And along with the issue of low-grade, impure inputs, it’s one of the many reasons to avoid cheap agricultural fertilizers claiming to be for cannabis (which are most of the fertilizers marketed to our industry).

Fortunately, steering clear of fertilizer contamination and toxicity is an easy fix: feed with Advanced Nutrients.

The Advanced Nutrients base nutrients (like Sensi Professional Series water-soluble powders), for example, contain precise amounts of copper and other macro, secondary, and micronutrients your crops need to thrive while safely avoiding toxicity.

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.
