I have my light out during the warm part of the afternoon. Today, right after lights comes back on, I opened my cabinet to see my plant with limp droopy leaves. After the light was on for a while, the leavesperked back up. On closer inspection, I saw this:
Is this overwatering, underwatering, cal/mag deficiency, overfeeding, underfeeding, something else or nothing?
Quick rundown:
They're at Day 21. They're in
OF. I used bottled water at 5.8 pH. I use AN on TaNg's easy auto feeding schedule. I am feeding 200 mL per day with 1.5 mL/L of Sensi Bloom A & B and 1 mL/L of Sensi Cal/Mag Xtra. My babies are in 9.2 L air pots. Temps are between 72 at lights out and 83-ish with lights on. RH is 60% to 63%. They are in a 1.5' x 2.5' x 3.75' (80 cm x 45 cm x 120 cm) cabinet. I have a 135 watt QB 288 light.

... I get "night droops" on occasion too, the lights-on perk up is the tell,..... that said, with OF soil which is rich already, and the feed inputs, you might be pushing the nutes too much,... other minor symptoms are too early and general to call out just yet,...
