What a cross, did you get that from seed? If you dont mind saying what breeder,please say! That looks as incredible as anything I have seen since DJ Shorts lines. Must be some high herb!!!
These are pics of a clone called "The Black" (not from BCBD seed stock) that I used to run years ago. It doesn't need cold temps to turn color. The purple comes out in week 2 of flower and only gets darker as it matures. Trichomes can even go fully purp if left long enough.
