I remember seeing those little things growing and trying to figure out if it was male or female. That area is where the hairs will pop out if it is female, but it is too soon. Maybe a couple more days?
with some strains it takes a while to tell and even then some you wont tell until up to the first week of flower but ive had a few that would show male sacs in like week 4 just depends on strain but after a month of veg and u still cant tell start to flower
