the hairs will turn brown and new ones will probably pop up. if you dont really see milky then she probably isnt. they do get noticebly more crystally and will then look more white in pictures.
if you are itching to cut some, i would recommend taking a few nugs off you think are most ripe. I usually do a partial harvest and it really helps. by the time i let a few nugs dry and have them start curing, the rest of coming in and getting a few more weeks to finish things up
