Drooping leaves

[steppedinds]

my babies start to droop 1-3 hours before lights off. are they just getting rdy to sleep or do you think this is a watering or air/heat issue? i havent narrowed an exact time to when they begin to droop, but it is at least 1.5 hrs before lights off. link to grow in sig. i'm thinking 18 hrs is alot for flowering, even for autos, and they are just getting rdy for sleep

I know this is an old post, but there were not replies. you may have worked this out, but just in case. They will do this. They "rise and fall" throughout the day. They seem to get used to their cycles and "expect" lights out and start preparing for dark.

yeh i think they were getting used to swapping to flowering on 18hr schedule. once flowering kicked in strong they stopped drooping so early and would reach till just about an hour before lights off.
