This may be a little more accurate in description.

100% Clear is week quick head high and will not last long.

100% Cloudy is heavy stone and will last longer (start of peak harvest)

80%/20% Cloudy/Amber is pure peak harvest heaver head and couch lock stone will not last as long as 100% cloudy but is stronger. Anywhere in between is fine and up to you.

Amber Trichomes are dead or dieing. If you pick at 100% amber then you have past prime and the quality of the effect is degraded.

When you check them it's best to harvest on the average with in your field of view and by checking on several parts of the plant and not just one or two places.
