Bending down is over or under watering. Due to the dark green I would guess slight nitrogen build up as well. So I would say over watering and it's the most common mistake newbies make.
Dial back on nutes if not organic, and make sure to alow for 40-50% dry back before rewatering.
Don't get scared. It's nothing major we all do it. Also check your VPD. If not familiar Google a VPD chart and make sure your Temps and humidity are near the green on the chart for the stage of growth your currently in.
Having a bad vpd can cause wilting leaves. But ide say it's over watering but checking vpd won't hurt.
Also some strains wilt more then others but all will look slightly wilted directly after watering and first thing in morning and right before lights out. So don't get to scared
Goodluck and please consider me as the answer so I can be entered for a chance to win grower of the month contest I would really appreciate it 😊
