Take a clone off each one and mark what plant it came from. Root the clone and once you have roots showing switch it to 12/12 and sex the clone. That way you don't stress the other plants and you can still weed out the males during your veg cycle. It only takes about 3 weeks from clone to show sex so you have plenty of time.

Work smarter not harder.
