I'd say you still have 1-3 weeks to go.... most of the trichs are still clear. If you want a purely cerebral high with no relation of body, you'll want to harvest when they're all milky. If you want some relaxation in there as well, then you'll need to wait until 10-20% of the trichs have turned amber... if you wait longer than that, you'll be locked on your couch... so it's just going to depend on what it is you want from your weed.
Good luck!
