OK so I feel like I'm looking at trichomes on the leaves here rather than the flowers. So I'm gonna start off with that. With that said, the leaves are usually pretty amber when it is time to pull and at that point, in my own personal observation of my grows, that I find about 30% amber on my flower which is when I like to pull. In addition, I was told recently by
@Rexer I believe, that when judging readiness, we should gage that from the calyxes, even moreso than the flower buds themselves. So, maybe try to get a pic of the buds and calyxes and let's re check!
