Is that just 1 pic taken 3 times? If so, I don't like the look of it. But it could just be a mutation. As its early just keep an eye on it and any fans you have blowing face it so that gets the tail end of the wind.
Keep any eye on it. Now, if she's a regular seed. What you could do if you are still in veg is pick a node and try blacking out that 1 node so it only gets 12hrs of light and you'll know its sex in a week or 2. Now, I've never done this, but I've read and heard ppl doing this to find out sex in a plant they wanted to keep vegging..
Hope this helps. Good luck.
