Had 2 from seed, both turned purple around week 6, and by week 9 pretty much purple everywhere including the calyx. Both slightly hermied tho.. Are yours from seed or clones?
Dont let the temps go above 85 tends to not purple very quick if it reaches a hot point, or completely. Usually begin turning purple round week 6-6.5, was fully purple at 8-9, so long as my temps stayed appropriate.
Yup, temps have a lot to do with it. My buddy runs the strain and it turns out better(or more purple) in the winter months. Sometimes he gets almost NO purple during the summer.
still no signs of color yet, i dont know the exact date but I about finishing week 5 and hoping for some color
unfortuantley, I am battling hightened temperatures average of 85-90 so I may not see any according to above :/ will post some pictures of the progress to for more input
