It will take a week or so to get back fully into veg but its safe . It will just set them back a bit in growth . But your probably wasting resources on a few(1) male(s)
If there not rootbound in your pots now you got time to play. Once you have a strong female you can clone her out and fill the rest of the pots anyway
Its what im doing right now with my seedlings. From what i know its general practice.
Btw you can transplant while there in flowering if there big enough and your ready to flower. If you still want them to bush out a bit go back to your veg cycle.
