You're probably early in the harvest window. Not quite at the highest THC content yet, and almost no CBN. I would go at least another two weeks based on what I can see, but its hard to say without seeing your trichomes or knowing the environmentals.
Without seeing trichs can't tell but if your plant has an 8 week flowering time and your at 8 weeks I would go at least 1 more then chop its better to harvest slightly late than slightly early
