light cycle question

lets say you switch from 18/6 to 12/12 but you started 18/6 from lets say lights on at 9am and off at 2am and when you switch over to 12/12 and had to do it 9pm lights on to 9am lights off would that cause any harm?
I only ask as I'm in a diff spot where I have a little less ventalation then my previous spot, and as the temp outside started to hit 90 degrees the grow area has been around 84-85 so I decided lights on during the night would make it a bit cooler. I have always just slowly knocked the off time down 30 minutes a week at a time untill I got to 12/12 instead of just straight to 12/12. So is switching the whole schedule around going to cause a problem? thanks

Won't matter. Just give them 12 hours of consecutive darkness and the flowering process will start.

Good luck

When you switch, I would leave the lights off from the normal 2am and reset the timer for the light to come on at 9pm and off at 9am.
