Can I Change 12/12 Cycle Time, Day 3 from Flip?

I flipped three days ago from 4pm-10am (18/6) lights on to 8pm-8am 12/12. I see now that it would be more convenient for me to water, prune, etc, if the 12/12 lights-on period was 6pm-6am.

Is it a problem to make that 2 hour adjustment 3 days from flip? I don't want hermits.

Thanks again everybody

No, it's not a problem.

Yup. No problem.

Theoretically, you want to maintain your 12 hours of darkness. I.e., turn your lights off at 6pm before starting your new 6am to 6pm schedule.
The dark cycle will be unaffected, although if probably doesn't matter much at that stage.

Thanks guys. I just adjusted it.
