I never bothered with trics. Just waited till it looked done. don't care if there were too many ambers or clears or yada yada, i just waited till it seemed ready and was never dissapointed with the smoke. If that was my plant, (it depends on how the plant looks as a whole, not just the top, then i'd probably be thinking 1-2 weeks more. this isn't advice, simply what i would do.
