Harvest close but yellowing fast!

Don't fret! Your plant is in great condition. Cannabis color can fade towards the end of its lifecycle. This is a great indication that your plant is using up all if its extra nutrients stored in the leaves as it nears the end of its life. Trichomes on the Sugar leaves will be the first to turn Amber. However, the process is not as "clear" (pun intended) as previously thought. Research shows that cannabinoid biosynthesis is still occurring faster in light amber trichomes than THC is degrading into THC. This means only when trichomes turn a solid dark amber does THC start converting quickly to CBN. In short, you want to limit the amount of clear you are seeing, and maximize the number of solid white/light amber trichs. The percentage will differ among cultivars, but to answer your question, I would not worry about letting these go at least another week, possibly more. You take brilliant photos of your trichomes, try to focus on the buds and don't worry if some sugar leaves are dominantly amber trichomes. If you want more information on the most updated info, this article and specifically Dr. Photons reply should shed some light on an otherwise *unclear* topic.https://www.cocoforcannabis.com/community/main-forum/when-to-harvest/
