Need help I’m growing in pro mix moisture potting soil and a mix of top soil and perlite 50/50 blend. Gorilla gelato auto Barney’s. Ts 1000w.18/6, what ph level should I be watering and feeding with? I started off at 6.5 ph but she wasn’t responding well and was real light green. I am now watering at 6.0 I gave her a little grow big fox farm. She is now 20 days.
