Here's the deal, I have 12 plants, 6 of one strain 6 of another. I am using ProMix BX with 25-30% added perlite. I mix all my nutes in a giant tub then give each plant 1 gallon. So they all are potted in the same medium and all get the same amount of nutes at the same pH. Today I watered with plain R/O water and tested the individual run off pH of all the plants. The pH ranged from 5.9-6.7 and everywhere in between. Why do all the plants in the same conditions have different run off pH?
