By the time this happens, it can be tricky to determine what the root cause was, but if you simply pH your nutrients from the start, you can avoid this mess altogether! With pH in the right range, your plants will be able to uptake all the nutrients you feed them, and meet their full potential in terms of yield and potency. It takes just a few moments, and can make or break General Hydroponics pH Test Kits make pH testing easy. Fill a test-tube halfway with nutrient, add a few drops of pH Test Indicator (Use 3 drops per 5mL of solution), and observe the coloration of the liquid in the test vial. Many experienced growers prefer our pH Test Kit to expensive electronic meters because it is reliable and easy to use.
