As far as the trichs go, it's really a matter of what high type you like. For instance, in my sativas, I wanna keep that head-thumping, heart racing high for daytime smoke, so I always cut when I see that he majority of the trichs are cloudy. For a bedtime smoke to help stop my mind from racing from one thought to another, I prefer an indica obviously. When I cut an indica, I will wait until the thc has degraded to the point that most of the trichs are amber.
One last thing to remember Turbo, is that most strains will show you multiple "harvest windows". That is, there are more than just one "right time" to harvest. Again, it comes down to what you want in the high.
For your particular situation, I'd say that your plant is exibiting signs of having entered that first harvest window. If you want a little body-effect to the high, I'd feed it water for another week, then check the trichs again. Your mileage may vary...
