I would say you can take it anytime in the next week. Today, tomorrow, the next day... The window for harvest is open. If you want to get the absolute most out of it and like the stoney couchlock type buzz let her get a little more amber. Maybe chop some now and some when shes a little more amber and see the difference for yourself. It's pretty amazing what a difference a few days can make in the type of buzz. I have one friend that likes to chop his plants in daily increments. Then he compares the smoke when it's dry. I have had the opportunity to partake in a few of his testing sessions and I could definitely tell a difference in most of his strains. Some of the indicas he likes them better on the early cloudy trichome side, some of the more sativa leaning hybrids he likes to let go longer to get a bunch of amber. Gotta watch those trichomes though, I have had a few strains like GDP that would go all amber really fast, like overnite.
