I would take a small branch and dry it immediately for sampling, you could find out that this is the stage you love the most - or you could confirm that it is too early for your taste. Harvest-timing is really hard, I've grown for years and still the only way I can gauge when to harvest is by trying different times. You'll be surprised by the difference a week can do at this late stage. For example, my current strain gives the best high before the thrics turn amber - and I would never know if I didn't try it. And I go for couchlock too.
