i currently have two plants, not sure what kind no pictures, but my plants are about 3 wks old thick stems nice fat leaves and one is already stinky... id say about 8 inches tall.... i am close to raising the lights bc the are almost to the top... any way i was wondering how to prune... which branches do i cutt? some have 7 leaves and some have 3 leaves... do i cutt the ones closer to the bottom? which look fuller? at this point i am unsure if they are male or female but look totally healthy.. i am confused i need some pictures...any advice?

None of the above, you don't cut anything unless your topping or fimming which you can chose to do or not for 2 main colas instead of 1 however you don't need to prune anything until it starts to flower..
