I was told by the Guy at the grow store I can sex my plants in veg stage. I thought had to wait for flowering. Can you in fact sex plants on veg that be awesome
A plant has to reach a certain point in sexual maturity before it can be sexed. Usually not until the second week of flower or around 6 weeks old. And yes, clones an be taken and pretty much thrown right into 12/12 to determine sex.
