Looks like a girl to me. There are ways to stress it out bad enough to flip it to one of them he shes or even all the way to a male but as it is looking right now, it's all girl. Your last run looked really great. Temp stress and a light timer screwing up or around might cause issues but if you stay with the same game you just got done with you should be fine. Depending on how fast you go through weed. I would let it branch out and make how ever many clones/branches you need and start another run with that. Great work you've done so far. Have you chopped your current run yet?
