its usually a week after what they say,also you start the count when 1st white hairs appear not at flip.12-12
cloudy trichs peak thc,amber degraded but different high.
up to you.
It really depends on the high you are looking for when to harvest. If you want a total body stone then wait til the trichs are amber. If you want a cerebral/body high, then harvest when the trichs are cloudy. Good luck.
If you want a speedy kind of high and can handle anxiety go with clear with some cloudy. I never used to get anxiety from it and loved the speedy high.
