I water mine again on Friday so I will do a final pruning and let them grow. Some people say don't prune during flowering but I do it selectively during the first 3 weeks and have no problems.
I was the one who originally gave him the idea and just wanted to verify it. I say it's fine. And I have been growing indoors for 20 years and have lost power for a day plus during flowering and just resumed normal schedule without any bad effects.
