harvest based on seed and pistil color?

my scope wont zoom in on my DP it works for another. can you base a harvest on seed and pistil color? most a turning brown. the yellowing of the leaves in an indicator of harvest is almost neat and some of the seeds and turning brown. the others are still green. which is why i dont want to pull yet. im thinking a week. its frosted but just. kind waiting on the trichs to get taller, but is this the kind of strain that had big resin glands or are the comes pretty small on this?

Yup 5-7 days and you should be ready. Harvest at the kinda high you want if you want couch lock harvest later if mixed then Id say 5 days.

Trics are the answer. Don't let the plant go too far into amber (5-10% Max).

• The third state is amber. Amber trichomes contain degraded THC --> CBN. CBN represents a loss of 90% potency (from THC).
  CBN is not desirable in any harvest, since it not only represents a huge loss of potency but research into the substance has also shown that CBN does not produce a high like THC does, CBN produces a more sickly feeling not a true high.​
