How bad did I screw up?

ABsolutely agree: environmental stress can cause it.

I think we've all done it, and kicked ourselves really good after that and didn't let it become a habit.

If there was a dope slap emoji, I would apply it here. All in good fun for better growing.

I think it takes doing it repeatedly. But if you're doing that, you're probably making other mistakes as well, all of which can cause hermie.

I can't even count how many times I've done that and NEVER had a problem

[SoOrbudgal]

I would do as the others have said, keep an eye on it and keep it going as if nothing has changed. Just watch it, I would grow it out.

I have had this happen, nothing ill came of it, but as said watch closely!

Pre-facing this by saying I've never grown cannabis indoors but I know a a fair deal about botany in general.
12/12 for over two weeks is enough time to begin producing enough hormone that causes the bloom. This hormone is only produced at night, hence why we increase the hours of darkness to flower. 24h of constant light.. like alltatup said, the chances of them either revegging or becoming hermies due to stress are big. Or you could have a super sturdy strain on your hands and it could just power through it. Keep a super close eye on them.

It may very well mess up the flowering hormone and your plants may go back to vegetation stage, or they may turn hermie. Here's more information: https://www.growweedeasy.com/cannabi...tal-re-vegging

How long did the timer malfunction happen?
If you caught it the next day and you corrected it, then I don't think that you'll see any effects.
Overall, just continue on.

My plant is 8 weeks old and has been on 12/12 lighting for a little over 2 weeks. I accidently left the lights on for a 24 hour period. Anyone have any experience of that happening and what I should expect from my plant next?
