Left lights on for 3 days during flowering

just give them 12 dark and then continue as normal. Theres no way to tell but i think you will be fine..

Had this happen to me(not that long but 24+) as I funked with my timer and didnt realize I turned it from auto to just on and lights never went out. Like saldaw said just continue on with flower as normal... they may be a little stressed and bud growth might be a lil slow be theyll unfunkatize themselves

That is literally exactly what happened to me. I certainly hope that they aren't messed up because they look beautiful right now.

I had my light go out, 1000 watt hps, replaced it with a 1000 watt mh until then, I don't think it stresses them too much either way, I think you will be okay, as long as they seem to get there 12 hours of darkness.

Good question. Be sure to post the results, it would be impressive if the plants shrugged off that big of a lighting error and continued flowering as normal.

for that long i would expect you to have some issues. at least some strange growth from trying to reveg. at that point of flower that is a long time.

You'll be fine.

You dont have a timer?
