Six weeks is probably more realistic. Even in 3's you'll have some problems. If it were me I'd root prune them and put them back into fresh soil just as I flipped them. Its the young, finer than hair, white feeder roots that do most of the mineral and water transport work. Those roots are at the very ends of the root system. They do all the cation exchanges, the give and take that goes on between the life in the soil and the plant. Without those ultra fine hairs the plants won't grow nearly as well and the end result is mediocre buds. Those fine roots don't grow in week soil. They need lots of O2, water and fertile medium.
So keep the soil fresh and fertile with top dressings and compost teas. You wont regret the extra work.
Good to know so do you think that might be a little to long of VEG for them in 3 gallon air pots cause Im probably not gonna transplant them out of these. Maybe close to month in a half maybe? And Massive Colas Is What Im trying to Achieve! not trying to rush it.
