if u have a good microherd in ur soil u shouldnt worry about ur ph, ph up and down will kill off ur micros, dont try to ph adjust ur teas either, the microherd will take care of ur ph if ur growing all organic and dont use alota organic liquid nutrients then u should be fine, let mother nature do her thing, and fox farm big bloom is the shit!! if u do use alota liquid nutrients u could get a bad affect, not guranteed tho there is a big debate going on if the organic chelating acids in organic liquid nutes will affect the micro herd, idk fasure and both side of the arguement have good points, but to be safe remeber tha old liquid nutrient rule, less is more, if u got a good soil mix u should really only need to add liquid nutes to correct nutrient deficiencys or if they are longer flowering sativas and theyve used up the nutes in soil
