So essentially what you will be looking for when trying to determine sex would be at the internodes , there will be anthers and behind the anther will be the sex organ being either male or female . Female sex organ is shape like a tear or a half moon and has hairs coming out of it , the male organ will be more rounded and will also be raised on a tiny stem ( somtimes its hard to see ) and often times male organs are random and show up in various places where they arent supposed to be at all but you will deff be able to tell the 2 from 1 and other one being that it has hairs and the shape is way different and the male is rounded .
I hope this information is helpful to you on your quest to determine your plants sex !
