What PH and EC / PPM hydroponic plants like. 5 to 6.5 Ph. This is because minerals like phosphorus in nutrients become soluble at that PH range. You can use an EC tester or TDS tester(PPM) to measure amount of nutrients. For EC / PPM 1 EC for seedlings(700PPM)then 1.5-1.8 EC as they get bigger (1050-1350PPM) and as they are full grown and or flowering 2.1-2.5 EC (1470-1750PPM).
