My plants are drooping also I have a flood & drain kit, hydro. There 4 weeks old looks good but droops at the end of the day. But when the light comes on and I check them they salute me, Lights 18/6 turns on at 3am-9pm when it starts to be at the end of their day they droop. I water 4x's a day for 15min @ 7am 11am 3pm 7pm then they droop like around 5pm. Im a ambitious noob so I did something also that I think made them droop today. (stupid) I put Orange peels in the room thinking it would make them more potent cuz I get garbage weed from my guy and I put Orange peels in the bag then it comes out a real good high in a couple days. So maybe that did it. Well I think it did. Then yesterday I think I overwater them cuz I was doing some test, and I didnt think I was overwater them until I seen them drooping then I started to think why and that was why. But the day before I didnt do anything and then one was dropping. Temps 72-78 humid 37-42% I always check ph @ 6.3. Fan is going. IDK please give me some help, pointers + rep to good advice thanks riu friends.
