that what i was kinda thinkin too, buuuuut, it looks like a ball forming .. no other "new growth" lookss like that on the plant.
maybe, I wouldnt be shocked if it was male, but those could just as easily be new growth. We dont want him chopping those down just yet.
Too early to tell. Be patient. Females will only have one on each side for the first week. Males will start out as a pair then start multiplying like crazy. If I had to guess B is a male.
Any update on this. Mine are just 5 days in flowering and I have the same thing. I do hope its just preflowers about to pop out a white hair.
Plant "A" looks like a male. "B" could go either way. Females have little balls like that where the hairs come out at. You should definitely be able to tell in another day or 2.
