Harvest pointers?

These ladies have been in flowering for about 7 weeks now. I'm wondering if anyone can tell me if they're close to being ready to harvest. Unfortunately I couldn't take any pics through my microscope, but the trichomes appear to be about 70-80% milky (though I haven't seen any amber yet).

You're pretty well there, what kind of high do you like? My preference is an energetic head stone, I wait until I see a few amber trichs scattered throughout and that works for me. Check out the link dadio put up for more details.

I also like a more energetic high.
Thanks guys.
