So I don't think the tiny lights on your power strips/timers are going to be the problem.

A big topping of the plant like you gave it, is probably what caused the stress and then causing it to hermie.

I also prefer a warmer room during lights on, but don't think that's your issue.

As far as switching from veg to flower light times, a lot of people recommend doing at least a 24hour dark period before flipping to 12/12. I've tried it several times and didn't seem to make a difference in how quickly flowering starts nor did it increase bud size
light can be an issue however it has to be significant enough. as far as night for a day or two, i dont see it as relevant. the switch in an artificial environment is as fast as it gets. in fact id say it confuses the natural program(as far as quicker flowering). many trials were tested on overgrow.com, whether days of darkness at the end of flower was productive. no evidence from anyone suggested any monetary gains. so i can only conclude that results would the same yield from the front end. each to their own though:jointsmile:
