Hey, I'm no expert but from what I can see, I would certainly say they could do with a little more time. Still alot of white hair, which wil only grow further so for now I would give them a least another week. Its all depends on your environment and light etc to give you an accurate date. When I grow I also wait for all my white hair turn orange from head to top of plant. They generally will show you they ripe and read nugz
