left lights on during flowering

I'm 6 days into flowering and messed up by leaving the lights on all night. I turned them off 7 hours after they should have gone off. What should I do now? What will happen to the plants?

Only one night shouldn't be anything major but more importantly.....go to walmart and get yourself a $7 timer, they even have mechanical ones for 5, i got my digital with 1 minute intervals for like 11 bucks, save yourself alot of headaches and worrying, if u didn't do 24/0 in veg im impressed youve kept it up, been quite an avid parent with plugging/unplugging

No reason to be impressed. I have a timer, but I turned the lights off temporarily and then didn't reset it properly.

They will only be a tiny bit stressed. Leave them in the dark for 24 hours, then start again. This will put the stress to a minimal.
