lighting schedule

[Zander13]

My canabis are in the flowering stage and should be finished in a few weeks. I have them on a 12/12 lighting schedule it comes on at 9pm and goes off at 9am. today I came home at 530 pm and my light was on for some reason. I would like to knw how and if my canabis will be affected in any way?
