Heres some green crack optically zoomed via microscope. It was difficult to get a perfect image. Here it is anyway. Hint: When approx 10% of the trichrome heads turn dark amber, your plant is at its max potentcy.![20180206_134931.jpg(

The life of a trichome can be analogous to a parabola, where the apex represents the point at which maturation exceeds and degradation begins. For the most part, trichomes will display maturation on this parabola by changing opacity from a clear translucent state to a cloudy white and, later on, amber hue.
This transition of color within a trichome head represents its peak ripeness and farmers typically use this as a sign to harvest, as it’s the point when the trichome has reached full maturation and will begin to degrade from this point forward.
