Plant leaves seem lifeless, droopy and paper thin. 4 weeks old, using ro water with calmag and recharge , watering till runoff then letting soil dry 2-3 days before watering again. Using a mars hydro tsw2000 soil is fox farms ocean forest and happy frog with dr earth flower girl and dr earth all purpose( I just amended yeaterday.) temps are 75-80 lights on 68-70 lights off. 20/4 light schedule. Perked up yesterday when I watered but then was looking sad again today. Been making sure not to overwater atleast I think I have. Any help would be greatly appreciated.
