The problem with asking people of a strain is done, is that the answer is subjective. If you like a more stone, you have to hope the plant gets more stoney when more tricks turn amber. Really you only know what characteristics the plant will show when tricks turn different colors is by growing, cloning and taking it different length. Or just staggering your harvest. My buddy just harvested his purple diesel, receding red hairs basically withered away, dense buds, and a decent amount of amber trichs. The plant to the right his space queen, is spitting white hairs, left and right, but trichs are amber and cloudy. So pistils are no indicator, and trichs aren't congruent with how the rest of the plant should look. The truth is, there is no right answer; but there are wrong ones. Under developed trich head sizes are wrong. Swollen heads are the minimum indicator. DJ Short recommends all clear trichs if I remember right. Different breeders say different things. This isn't a one size fits all. The answers are subjective to what fits your wants and needs, and how the plants ccharacteristics are displayed.
Otherwise the best people can tell you is a generic answer you could have looked up yourself. Unless of course you have a clone, and the grew the same cut as well personally, and can tell you what to do.
