3rd day of flowering, help!

3rd night of flowering rather, and I fell asleep with the lights on. I intend to install a timer today to avoid this problem again. But instead of the lights going off at 11:00pm last night, they were out by 4:30am. Normally they awake at 11:00am. Because of their extended day, should I let them sleeo longer, or just force them back on schedule?

Also, Il using my 400w MH lamp for the first week of flowering, and switching to HPS after that. I read this was a good idea, can anyone confirm?

funnny get the timer dude and just keep them at 12 12 for the rest of their lifes
