Looks dank for a window grow.Nicely done. I'd say you are very close. The pistils are still standing.Maybe 7-10 more days.
How long has she been flowering? What doe the trichs on the buds looks like....clear,cloudy,amber?
Leaves fading and dying is natural at the end stages of mj's life. Judge ripness by trichs,stigmas receeding,time in flower according the strain,and your preference.
Look up late flower and harvest pics of your strain to get a rough idea.
