How much longer do you think?

Yes leaves are loosing colours but it's mostly due to some nutrients related issues but you'r on late flowering so the next step will be a flush that will get rid of the excess nutrients in the soil and start a real yellowing . If trichomes are looking cloudy then it's probably because you are close from harvest even if she's pushing more pistols it probably means that she can builk up some more fore the growers who appreciate the weed with mostly amber trichomes Like you said 10 to 14 days flush included
