Check this out for some info http://forum.grasscity.com/absolute-beginners/873879-how-tell-whether-your-plants-male-female.html It sounds like you switched to 12 12 without it showing pre flowering.
Putting a plant on 12/12 before it is ready should not cause it to go hermie -- you can go 12/12 from seed if you want, that's a key idea behind a SOG. And you don't want a hermie, a plant that is stressed to hermie and pollinates itself often produces screwed-up offspring.
