I'm seeing white hairs on two of the three plants. The first pic is actually the only one I can't see white hairs on. Looks like it might be male. The last 3 pics are of the other two plants.

You can't see it in the pics but on all 3 plants the tips and serated edges of the leaves are yellow. Just the very tip where it comes to a point like a little dot the size of a grain of sand right on each point on the leaf. I think this is nute burn but I'm not sure. I'm feeding them Botanicare Pure Blend Pro Grow, Liquid Karma, and Superthrive every three days when I water.
