im in my last week of flower my temps through out the grow were 70-74f lights off 74-80 lights on. The past 2 nights I've upped my day time temps to 85-90f and lowered my night time temps to 65f about a 20-25 degree difference. Would that help my strains turn purple? I know there definitely in the genetics so just want everybody's opinion on how to turn your buds purple in the last week of flower.
