First of all that is your problem there. You don't smoke the leaves, as they don't contain much THC at all, they are a waste, unless they are clippings from a harvested plant that have tricomes at the base. You are going to have to wait until the days get shorter and the plant begins to flower to tell the sex. Go to www.overgrow.com and do a lot of studying on the cannabis plant and growing. If it is a female, you need to have patience and let it mature. Don't just pick the first buds you see. Study study study is the best advice I can give you.
