Changing 12/12 Hours Two Weeks Into Flower?

[Irietime]

so my plants are 2 weeks into flower and I was wanting to change my lights on time to 12 noon to 12 midnight. Right now they are 6pm to 6am. Is this a major no no?? Will it mess with them to much or will they be able to handle?? I know it's not ideal, but just wandering. Thanks for any feed back. Peace

I've done this before today with no ill effects but you have to do it a particular way so as not to allow the plants to believe they can reveg. Make sure that when you flip that you have them in a longer dark period to make up those hours, as if you flick directly after 12 hours of light the plants will think the days are getting longer and not shorter which is what we want them to believe so as they don't flip back into a vegetative state and hermie. I have no problems with giving plants extra dark periods at any time during flower, but never any extra hours of light.

Thank you. That was exactly the answer I was after.

Maybe that extra six hours of dark will kick them into drive. Thanks again @kraize
