Magenta hairs...temp? harvest? w/video

I am rl friends with another forum member who posted pics of this same plant, yesterday. I uploaded a video (zipped avi, link below) with *decent* night time penlight shots of the buds (and strange neon purple hairs). The location is windy as you can hear. But the plant is about 7 weeks into flowering and it has gotten colder here (mid to low 60's at night). I have a 30x pocket microscope that has almost arrived to inspect trichomes. But based on this, when should I harvest? Are those wacky colors b/c of a temperature drop? any input would be greatly appreciated. Also, enjoy the video. Thanks.
