In many cases, there's a hidden problem that blocks plants from absorbing nutrients. The problem involves what chemists call pH. This term describes the relative alkalinity and acidity of the water and root zone media your plants grow with.

If you want your plants to grow quickly and produce fantastic harvests time after time, you need to carefully balance the pH of your hydroponics root zone and nutrient water.

You've got to be a bit of a chemist to do this, and you've got to use Advanced Nutrients pH Up and pH Down to carefully regulate pH levels so plants can absorb maximum nutrients and grow well.

Acidity and alkalinity are extremely important factors in your crop's water and root zone. Ideal pH for your plants is 5.8-6.3. A pH reading out of that range indicates conditions that very much decrease your plants' ability to take in hydroponics nutrients, grow well, and produce large harvests.

If pH is too extremely out of range, your plants may die!
