Sorry, didn't read your two sentences properly. A ball on a stick indicates possible male plant. If it looks like a little bunch of grapes it's definitely male. You can kill it and cook it because apparently male plants as they are showing their sex can contain as much thc as a mature female, so it's not all bad. Doesn't smoke up too nicely though, or you can keep it and use it at a later date to seed a bud on a female, but get it away from your females asap.
