Plant in late flower accidentally left on 24hr on light cycle after swapping light because if malfunction. Thoughts?

If it’s that violator kush - you’re probably gonna have some issues there. It’s not close enough to the end that I’d say you will be able to ride it out and chop. Those still need a few weeks. I’d just switch back to 12/12 and hope for best but revegging process will have started - whether you can see it or not. It usually take 2 weeks to start showing visible reveg. Not much you can do but hope it bulks up a bit without showing intersex traits from stress It will be quite interesting to see what happens tho.
