Well they look beautiful. the only true way to tell is by checking the trichs, with a magnifying glass. They do look pretty green still, have you flushed?
iv been quoted 2 weeks to 3 weeks left on afghan and 3 to 4 on the ww the first pic is afghan and the second is ww no iv flushed every now and then to just shift some salts if they have built up but i will be flushing when most of the trichs turn amber: P
