Sorry, I have to step in here..... You can sex a plant at anytime, when you change to 12/12 it WILL change.... You can just check and throw it back in veg when it shows. It will slow it down for a week or two while it switches back to veg.
As for your males, here is a good read it should give you a few ideas.
Pollination Method
Umm.. Obviously you know there's a difference between a clone and a seedling. A seedling will not show sex until it's sexually mature. Pushing a seedling to force sexual maturity by putting it under 12/12 before it's DNA ready(IE a two week seedling at 12/12), won't cause flowers to show up any sooner then they should.. Ever. Several people have theorized that it actually stresses the plants out and induces more males and hermies by putting the lights in solid 24s or putting them in 12/12 too early as both of them stress the plants out more then they're accustomed to in nature.
All clones are sexually mature because.. well, who the hell would clone an unsexed plant?
