So this is what happened: I switched the lighting manually to 12/12 lighting to start the plants flowering. I was going to buy a timer, but thought it'd be ok to do it manually for a couple of days. After two days I had to be out of town on very short notice. I did not have a timer and no one I could rely on to check on the plants twice a day to turn the lights on and off. So I just left the lights on and left. It's been a couple of days and the plants seem fine, how long should I wait to switch the lighting back to 12/12?
