Messed up my light cycle

I had some issues with my timer last night and the lights never went off. They were on for just about 24 hours before I noticed and I immediately put them in the dark. They're about a month into flower. Is this going to mess everything up? What is the best way to get them back in the cycle?

Just reset times you were running, one misstep shouldnt bother the plants.

Great thanks for the reply!
