Sorry I couldn't type for some reason... not sure? Where the stem splits at the bottom what's the growths coming outta the side? 3 weeks into flower..
A plant will show sex when it's about 8 weeks old during veg...if you know what to look for. But if you're already into flower that far and you haven't seen balls, the chance is pretty much over unless you stress them too much and force them to make seed. TWW
