My soil ph is almost 8.0ph... plants aren’t taking up nutrients and are yellowing out quick. I thought it was low nutrients but that mixed with this root zone ph being 7.5-8 I think could also be issue. I’m at day 42 of flip and was reading on Aluminum Sulphate being used to lower ph in soil. Is it safe to use? And will it work fast?
