clone question

so i've taken my clones, they have rooted and i was about to transplant one out of the solo cup i started it in when i noticed a couple pistils with hairs and was curious, how common is it for a two week old clone to already be showing its sex? Even when it was a part of the mother it was never put into 12/12

The mother must have pre-sex showing as well. Are you sure those weren't taken from a flowering mom? Sure looks it.

the mother was on a 18/6 schedule her whole life until after i took the clippings, although i was surprised because since planting her outside to flower naturally shes already showing a very good amount of hairs so its possible that my timer got screwed up or something, this is my first grow and so far its been fun but a pretty tough all the same, ive had almost every problem you could think of except for spider mites thank god

My plants start showing sex before they go under 12/12. I run only feminized seeds and clones from my fem plants so that may have something to do with it as well.
