2 white hairs, all good in th epicture provided. Can't comment on the unseen.
google image search "marijuana" with "calyx" and "pollen sac" ... it's easy to discern between the two unless it's very early on. Notice the difference in how the leaf envelope looks and you can distinguis before the hairs pop out, too. The male envelope is segmented at several points where it will eventually split open, and the calyx envelope is more of a wrap around with a couple overlapping 'seams'. for lack of a better vocabulary - more of an angle and much harder to see compared to a bottom-to-top vertical seams of the male segmented envelope.
A magnifier and razor blade can slice one open and look inside even earlier to determine gender -- 2 folded up hairs or a row of naners inside.
no worries, you have plenty of time to use the naked eye to pull the plant or pluck the sacs before any pollen hits the air..
