some strains no matter whatcha do seem to stay on the milky/cloudy side of color.Ive had a few strains do that eventhough they are plenty ripe.in my dealings(your pretty far along though)Id run CO2 and lower the light time to around 10 hours on,and push the light a touch closer depending on what yer using ofcourse.but if it were me,Id just flush for a week really well and harvest.but thats me at 13 weeks and no amber,Id flush n chop."AFN smoke out"
