I'm more of a noob than you, and I appreciate your input. I don't think it's a good idea to change light cycle heading into week 6 though. They're all flowering already, including 3BOG, and it would most likely cause some adverse effects....
I agree with u @Eyeoftheworld if you are going to change light cycle need to do it early like week 2 or 3 IMO... I run 24hrs until week 3 of seedling then they get a 4 hour rest for the rest of the cycle
