Your photos are of trichs that are on leaves which aren't reliable... Yes, there are some amber, but I ignore those if they're on the leaves.. you need to take a look at the trichs that are on the buds themselves.... Have the pistils started to turn brown? Has the plant itself started to fade/leaves turning yellow? These are the clues that will tell you to start looking at the trichs... pistils should be about 90% brown, fade should be taking over the whole plant...
Good luck...
