With my already sexed clones I actually clone before I flower (I don't keep mothers, I just take 3 cuttings per plant before placing into 12/12) You could do this now and I'll tell you why it makes good sense (to me, if you are patient).
Your first run with plants you don't really know how the plant grows, environment it prefers, notes. Since you didn't clone the tops (this is best when you clone the tops)' I clone all seedlings. If you get a couple males pic the one that looks best to you let it grow, pollenate your females, you'll have 100 beans to play with later if you need to move, have a disaster, god forbid cops take your legal grow (it happens). Just my 2 cents, but than again I like to breed
Of course once you know which are male and females you can discard the cloned males for future runs, unless you want to breed but that's another thread
