No. I bet the leafs do droop after lights out. Autos can be very tricky DLI wise. They do need a rest. As too much light slows growth. To induce flowering adding far red will help.

Auto dont care about light duration, she will mature enough ( or stressed ) she flowers. She will always flower, so longer veg is good sign, plus good harvest upfront. BUT autos goes hermie too, playing with day duration in my opinion is heavy red zone. Choose one and stay. 18/6 is optimal for autos. If to be honest i write 18/6 but by timer its always 17.5/6.5 at mines or so . I want for them to have those minimal 6 hours of rest 4sure. So i added a bit. Happy Growing !!!

If they haven't bloomed yet they're may be an issue in the genetics if those are autos...try the 16 hours for a week and if that doesn't cause them to transition then definitely go 12/12
