Leaves wilting at night

[fatbuds420]

Is it normal for leaves to wilt a bit at night?

I'm the morning they get back up normally, not a water issue, and temps are good

It’s normal, once the plant recieves all of the light it can use for one day it starts going to sleep regardless of the light cycle.

I've noticed some plants actually start to go to sleep about a half hour before the lights go out.
How do they 'know' that it's about bed time?

Yes, at 'night' they go to 'sleep'.
And they droop.
Normal.
