Is that a white hair on the left flower? I think it is too soon to show. You've got time, keep checking everyday. Those little nubs could just be new branches forming. Hope it works out.
If it is a male I'd say it's still too early to tell. Males produce these little stigma things at fanstem/mainshoot level at the point of which the stems come from the main shoot before they get balls. These are "like" two hairs but they are more greenish than white.
