It's looking close, you're probably getting into the harvest window if you prefer the less sedative effects of an early harvest. I think many growers would give it a few more weeks, but everybody has different preferences! I judge when to harvest by overall bud growth/development, and the change from milky to amber trichomes on the buds themselves (not the leaves).
Hope this helps, the plants are looking great! Happy growing! 👍🌱
