Hey hoolian, so i took a quick peek at your grow journal and its seems like your still in the earlier stages of veg, correct me if im wrong. Unless you have had lights on 12/12 or A LOT of electric issues where lights go out unexpectedly then you can be pretty sure this isnt a male trait necessarily. i can definitely see your concerns but unless you see signs of sexing (pistils, and pollen sack) on other plants this is just a wacky pheno...
Also sounds like these are regular seeds (not fem like your other grow) so if i was you i would chop off the top 5-6 inches, put the cut in a rapid rooter, coco, or whatever media you clone in and put the cutting into 12/12. This has multiple benefits, namely sexing that pheno, topping the plant which allows other lower branches to catch up/make an appereance, and also keeping your canopy a relative height.
Now if you just want to fix the height issue lower the light, lst (tie that bitch down), and/or top her.
Hope that helps, let me know! im going to be subbed in for the grow
