The thing is, in the two weeks after flip, the plant stretches. At the same time, it creates a lot of new root to support the bud sites that will be forming. If the plant runs out of container, you may need to re-pot. Do you have any larger containers if this should happen. You will know it is happening because they plants will look starved, and feeding them doesn't always fix bound up roots.
Can we get some root shots of the males as you destroy them?
