This post goes with above one. It explains how to look at trichs.

When using a magnifying glass or loupe to determine ripeness, you’re examining the resin glands on the buds for signs of maturity and/or decay. During flowering, these glands start out small and increase in size as they fill with resin. As they near maturity, the head of the gland will begin to expand and it will start to look like a tiny mushroom. This is the first sign that they’re nearing the point of diminishing returns. This is the point at which production of fresh THC laden resin has slowed and is equal to the rate of decay of THC into CBD.

The decay of THC is accompanied by a change in the color of the resin from clear to amber. This is the other sign of ripeness that can only be determined by magnification. What you’re looking for is the point at which the production of fresh resin is still just barely outpacing the decay. It’s impossible to know the exact moment. You just need to keep checking and go with your gut. 30 power magnification is enough to make the call, but 100 power would be easier to see clearly. You can find a loupe online by searching for jeweler supplies on any search engine.
