think about it this way, the resin that coats the bud that gets you high is covered with trichomes. This is the same resin that drips onto the trim leaves making them sticky and smokeable. If it takes 9 weeks for the bud to mature for the best quality smoke, then it will take just as long for the trichomes covering the trim leaves to mature into a good smoke.
I don;t know if you knew but to tell when your bud is fully matured you need to look at the trichomes under a microscope. you do this by cutting a trim leave off and examining it under a 60x-100x microscope. the maturity goes as follows......clear to creamy to amber. the bud is not worth much if the trichs are all clear i.e. until the last few weeks of flowering they start to turn a creamy color. then as the window for harvest closes they start to change amber
