hey so im going to start flowering my plants and I was just wondering if I should got from 24 to 18/6 for a bit then down to 12/12 or I read somewhere that I should shut the lights off for a day before I change cycles I just don't have a clue what im doing haha so any help would be appreciated
Just switch them to 12/12. Going down to 18/6 has no real effect on starting to flower. A day of darkness is pointless in my opinion because it really has no effect other than what switching to 12/12 has.
There is really no wrong way to do it, as long as you go from veg to flower and never look back. Don't stress the plant by trying to clone or trim it anymore though, just put it on 12/12 and keep it there. Just remember at this phase more darkness is better than more light, so if for some reason you have to choose between having the lights on for a day straight or the lights off, in veg you would go with lights on, but in flowering you go with lights off.
