I am a first time grower, In door tent 4x4, 900w led, coco/perlite, flora trio.
My problem is I’m having 2 of 3 plants that have leaves that are drooping every day, just the top third, a few hours before lights out. After feeding and lights out, when I check next am all looks great. The two will continue to look good for the majority of the light schedule, then after about 15-16 hrs (4-5pm) they start to droop? I’m running a 20/4 light schedule. Out 10pm on 2am. I feed about 1+hr before lights hour. They are all different strains. The third plant has done great. The plant doing well was the best germinated and the other two are about 1-1.5 weeks behind.
Long story short. They droop every evening, only the top 1/3. Every morning after a h20 or feed day they always look great. Doesn’t matter. I’ve doubled water and cut in half,no change. Also upped nutes, no change.
This is quite normal after a long light cycle. Much like a person looks droopy after a long day at work. I run a 6/2 light cycle and the plants don’t do this.
You don’t have to, but you really don’t have to run 20/4 at this point either, being autos they don’t really care about the light hours so you could go down to 12/12 or turn off at their droop point 15/9 or 16/8.
If you do some research you can calculate the output of your light and develop a grow schedule that provides the right amount of light per day without wasting it. After a certain point plants are unable to process more light and need some time to adjust.
