I have ten plants. Not sure what they are. 3 out of the 10 are showing sex. I kicked the 2 males out 2 weeks ago and just found out the third is a female. Plants are still under 18/6 lighting. I don't know why they are showing there sex already. My question is what do I do with the female only the top 1/4 is showing sex. Should I flower her or should I leave her under they 18/6 light? Please help!!!
