Judging by the fan leafs, your plant looks like a sativa dominant strain. If it is White Widow, it is probably a hybrid cross strain that is mostly something else. I dont think it is WW though, but it is impossible to tell for sure.

The hairs are called pistils. They should be a milky white, then change to a orange/brown. Once over 50% of the hairs change color, you can harvest your plant.

Doesn't look like a hermie to me. :thumbsup:

Happy growing....
