Real SECRET to Bigger Yields from Your Bloom Booster

Did you know that 91.7% of growers who use bloom boosters see bigger yields?

They see larger, heavier, denser flowers and a significant increase in overall harvest weight and market value.

But even with these benefits, there is still a challenge…

The Problem with Most Bloom Boosters Is…

…they contain poorly absorbed forms and incorrect ratios of phosphorus and potassium.

Typically, bloom boosters hold double the amount of phosphorus to potassium.

And if there’s too much phosphorus, it creates toxicity that destroys cannabis health and flower production.

During the bloom phase, plants are hungrier for potassium than phosphorus, so you need a balance of the two elements.

In fact, this is the one thing that trips up so many growers . . .

Who end up beating themselves up over larfy harvests . . .

Because they got the raw end of the deal on out-of-whack fertilizers that are improperly balanced for the crops you’re growing.

The fact is this: precise and appropriate ratios of potassium and phosphorus lead to larger flowers.

And when you invest in a premium biostimulant with optimal amounts of each . . .

You’re going to rake in buckets of profit from the huge yields and potent bud you’ve mastered.

Which is why…

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.
