Won't cider vinegar kill all the microherds? Yeah, I am having bad problems with my ph and I believe my one plant is mangnese def so I am looking for something for that. I should have added the lime directly to the soil, but I didn't. My plants are in day 31 of flowering and the one doesn't look so great. I think all the organics made my ph all outta sync. Can you use ph up or down directly in your teas without it hurting your microbeasties? Thanks for the help everyone.
