You are looking for no or almost no new white hairs. In the magnifier, look at the trichomes. Some people like their buds less ripe or more ripe. I like to see mostly cloudy, minimal clear, and about 20%-30% turning amber. Check the trichs on the buds, the trichs on the little sugar leaves will look more mature faster.
