I'm running organic amended soil and high doses of caps bennies. The only time I use a pH pen is for cloning. I never pH what I water in, ever. My filtered tap water is about 7.2. I've never pH tested the teas I brew. I've never pH tested my medium or runoff either (I don't water to very much runoff, plants soak it back up quickly). My assumption is that the microbes adjust the medium to their liking, so I don't have to. For my grow style I've found that while I still give the garden tons of love and attention, the less I actually do to the plants, the better they respond. While I do battle pests on occasion I never have deficiencies or lockouts. Anyway, to each their own.
