I can never trust calling a male in veg. I can call it female if I see clearly see a preflower pistil. I've had too many that look like little bumps at the nodes, and they end up throwing female pistils. I wouldn't call it male until I see definite clusters of male flowers starting to pop out, and confirm that there are no pistils. It could also be a herm. Only way to know for sure is put it on 12/12 for long enough to show sex. 7 to 10 days, and you should see the first pistils. If you want to make it a mom, put it right back on 24/0 light, and it will go back to veg growth pretty quick.
Cannabis goes to offset nodes at sexual maturity.
