This is an it depends, no? I have had ambering up on cure too....I always thought hairs being orange is time...although some do prefer to let em go longer for the ambering of the crystals.....On my indoor grow, I went 2 months on the flowering 8, 9 weeks, hairs were orange but tichs were opaque, not amber....Got a jewelers loupe or a microscope? Trichomes are my preferred method of testing readiness for harvest.
