2-4 weeks. Hairs will no longer be white. You’ll want to watch the trichs and chop when they are no longer clear, I wait until they are about 60/40 milky/amber. Pick up a jewelers loupe and you should have no problem. Make sure you’re looking a the trichs on the buds not the sugar leaves as those change color much quicker.

Looks very healthy. Great job!

Edit: here is a good pic on what I’m looking for. Also, if this is your first harvest make sure you have a plan for the dry/cure if planning to smoke/vape. It makes all the difference for the taste & smell. Cheers!
