How tall is your grow space? They look ready to me. If you've already started flowering I wouldn't go back to veg if I was you.
Looks good to me, although, I'd have to say if you can, while you still have the time before they bud, I'd transplant the one in the square container. If you have another container like the orange bucket, you'd be very pleased with the results. The more root space = more plant, and then more buds. If not, you will still do alright considering that it has a decent amount of space. But if possible I'd take advantage of more root space. EDIT: What strains?
