not being rude so dont take it that way, but i believe it's the trichome's that need to turn 2/3 amber, not the hairs or "pistils" if you brush those with your finger they'll turn brown, so i think that's a bad idea. you need a magnifying glass to look close enough at the trichome heads, they start clear when the plant start flowering and you'll see them develope and mature and become more visible to the naked eye. However, to really see it's true color you need to bring it out of the grow room and use a magnifying glass to inspect the heads of the trichome, they start clear then turn cloudy/white, then amber. pick it too early and risk not getting stoned from ur bud, pick too late and you'll be couch locked. Check out the faq, i'm sure they have some more info. on this, but pictures of buds aren't going to tell you when you need to harvest, all buds look different mature. Goodluck with the grow! and READ READ READ! tons of info. on this site!
