1st grow, 6 plants, this ONE looks *very* different. What is it?

I planted 9 "bagseed" seeds. Just random seeds I've collected. 3 plants died as I was learning the correct "formula" for it's environment.

6 plants survived. I kept them 24/0 Vegging for approx 3 weeks, and when I had a power outage (Well, forgot to pay the bill, lol) - And it left the plants with approx 10 hours of complete darkness, I took that as a sign that I should start 12/12. I noticed all the plants start growing a lot faster, and I've done zero "training" and I haven't "topped" any of them. They've been on 12/12 for a little over a week.

This one plant stands out. It was always the slowest to grow. She's my favorite though. I've taken some pictures... Is it possible to tell the sex yet? Those round things... are those signs of her really being a male? Or a tranny?

Any other comments/suggestions/opinions are very welcome. The other 5 plants, I believe it's way too early to 'sex' them. I don't really see any signs either way. Either way, I count myself as lucky for doing so well thus far. I realize that ideally I should transplant them to larger pots, but I'm experimenting and limiting them to party-cups.

Anyhow, here you go. First the overview pic, then some closer-up shots. All the pictures are of the ONE short plant. Click for the higher-resolution images.

Are those hairs on him/it? Could it be hermie/trans?

See this pic: At the very top, I see balls. The one below, no balls.
