For what it's worth, i think they are plenty harvestable, but I wouldn't call them done. They seem to still be shooting fresh white pistils to me, which I think would indicate that they are still growing. The majority of your density and weight is going to happen in the end, and If I were you I would try hard to wait another 2 weeks. In the end it's up to you though, and you have to follow your gut.

They look beautiful by the way :thumbsup:
