If you look at my CBD hydro very similar took her talk structure very early and hadn't changed in the way of shape she just got bigger and only in the last week she is putting on bud mass. 3 weeks left at least then check with jewellers loop or mini micro scope and wait till 70% cloudy 30% amber cause I'd wait for as long as I could to harvest her as she has her bud sites now it's just a matter of getting them fat, about another 30- 40% bigger they should get. Good luck.
