Not to be negative or anything, but I don't see pistils. I see leafs that are starting to develop. And many times the stimuli look like pistils when they start to grow. I think it's too soon. If that's that top of the plant, then that just looks like new leaf growth on a micro scale. If you had some better pictures that were more defined, but I don't know. AGAIN, I might be wrong, and I usually am. But from my experience, the start of female hairs actually looks like very thin, literally the width of a human hair. And I don't know if you're referring the stuff on the stem sticking out as "pistils," but they aren't.
