Hey 👋
I see a lot of milky trichomes, but still many clear ones and hardly any amber ones. So in my opinion, you can definitely leave them for another 2-3 weeks if you want to harvest more mass.
However, if you want to harvest at the THC peak, you can do that in 1 week. By then, you should have a few more milky and hardly any amber trichomes.
Hope it helps! Have fun harvesting 👋🍀👊
