By the hairs I am thinking girls but maybe its too early to tell (they have been in flowering stage for 1 week about). There is one that has a few little hairs and its the tallest (really grew up faster then the others) but not near as many hairs as the other 2 so im not sure. Chime in and let me know what you think if anything.
