What's a good link for close up differences?

i have a plant that looks exactly like that. what type of lighting are you using?

i think too early to say

yeah its to early to tell yet. what lights r u using and what time r u on. go 12/12 for a week and then see. look for 2 white hairs that form a v(v is for victory)thoughs little hooks that you see r on all pot plants

way too early dude, way too early there is nothing to see in therms of sex
