Rectify A Basic Nutrient Solution With General Hydroponics pH Down 1 Gallon! If your pH is too high, your plants will suffer as certain nutrients will get locked out. This can lead to deficiencies, stunted growth, and dismal yields. Plants have a very specific pH range they like - between 5.5-6.5. It only takes a few moments to test and adjust your nutrient solution, and it can make all the difference. A healthy plant will always yield more than one with pH issues! And when it comes to a basic (too high) nutrient solution, there is no better way to bring this figure down into the ideal range than with the General Hydroponics pH Down 1 Gallon. This simple acid formulation uses natural, food-grade phosphoric acid to help restore the ideal pH level.
