Ok so the second picture does look like you've let it go further than needed. Depending on the strain allowing the hairs to go from white to brown, orange, then allowing the mature hairs to fall off, then new white hairs will grow back then change colour, this is done to fatten the buds more. Sometimes it'll do what yours has done. Either harvest now or allow the hairs to change colour then harvest. Personally I'd let them mature then harvest. But I'd harvest the buds that are really and leave these one to mature again. This has been my experience. I hope this helps you
