Late flowering master kush

Hey guys and girls, I have a plant of master kush in late flowering (about 9 weeks). Shes got some nice big full buds showing all the signs of being done except the leaves are not turning yellow. Not at all. I stopped feeding it about 2.5 weeks ago. Just flushing with water. Thought for sure after 2 weeks of no food it would start to suck up the stored nutes. Nada. Any of you had plants finnish with leaves still green? All the past strains I've done indoors have turned yellow. This is outdoor. Getting 12 hours of sun. A little less now with the season change upon us. Any help would be appreciated. I dont want to take down too early and don't want to take down too late either. Thanks.

Gotta have pics bud.

Do you have a close up of a bud?

You're probably in the harvest window. It's all personal preference now. Check you're trich's with a scope.

Now is when the buds really need nutrition.
