I agree with hempsmoker on this one.

Give that a little more time to mature, check up on it, and your other plants (if you have more?) at least once a day I would say, just to see whats happening. If it were me I would be taking a magnifying glass to the sucker and seeing if I could see two little hairs poking out of that ball. Unfortunately males tend to mature faster than females and I recall you saying this one was your fastest grower so...

Good luck mate!
