Can anyone tell whether these are Male or Female yet?

I was just curious if my plants are mature enough to tell sex yet, males or females, that is the question. Thanks a lot.

drop in 12-12 for a few days if you really want to know.

cant tell yet m8 but normally shows in week 6 of veg or like said u can put into 12/12 another way is take cutting and put that into 12/12 so as not to stress plant with light changes
