Umm Im not 100% sure. But plant's know when lights off and on are going to be. They may just be preparing themselves for their night period. Or it may be from the rise in temp if its not that. As long as the leaves are healthy green you should be good.

That why you shouldn't change when your lights are off and on very much. It can stress them and cause them to go Lady Gaga (Hermi) on you or just end up being a male.
