The best indicator for harvest is trichomes, not how the leaves or pistils look. Leaves can sometimes appear darker, “burnt,” or perfectly green—it all depends on genetics, the strain, and other influencing factors. Trichomes, on the other hand, will always be clear, milky, or amber, and that’s what the harvest timing is mainly based on.
The ratio of milky to amber depends on personal preference, but from what I’ve seen, people often aim for about 80% milky and 10–20% amber. The plant looks healthy, has a solid root and the buds are a bit “skinny” (though that might just be the photo angle). As for yield, it’s hard to estimate, but I’d say around 50–80g dried, probably not more.
Best regards.
