I think you've got several weeks more - but the key is both the color of the trichomes and what YOU want from your smoke... Harvesting when the trichs are milky will give you a cerebral high... if you wait until there's about 20-30% amber, the effect will be a more rounded cerebral AND body high... if you wait and harvest when they're pretty much all amber, you'll get couchlock and the THC will be greatly degraded... So figure out what YOU want for your smoke and check the color of your trichs... if you don't have one, you can pick up a jewelers loupe fairly inexpensively - make sure it gives you at least 30% zoom....
Good luck and good smokes!
