I have a Canon Powershot SD750. Its a 7.1 mega pixel. Its not the best camera in the world but its not the worse. Attached is a picture i just took this morning. If you open and expand the picture to its max size. You can actually see the trichs reflecting light and the color as well. As you can see most of the amber trichs are further away from the bud and on the suger leaves. As the plant ripens they will continue to work their way up closer and closer to the bud and will fill in more and more. I really honestly think your just not seeing them or looking in the wrong place. 11 weeks with no amber tichs is really really really really odd especially on multiple strains and plants. The bud in the picture is 5 weeks into flowering and already has at least some amber.
