If you saw the first white hair on july 5th and now you can't really find any/many white hairs, you are doing something wrong. That is more then 3 weeeks of flowering and you should see white hairs everywhere. You should keep the plant in 12 hours of light and 12 hours of darkness for it to flower. It takes about 7 to 8 weeks for an Indica to finish flowering and 9 to 11 weeks for a sativa to finish...
