So I see a lot on-line where people often recommend to use cold temps to get buds to turn purple, but I have also recently learned that stressing a plant, especially a strain known to turn purple will do a nice job too. Specifically, things a little higher on the high stress training side of things, like pinching a branch down early flower. To me this seems a lot less harmful than colder temps at night and was glad I found it to work... I've also seen them go purple when they are seeded up, and also not from seed, but then a clone will do it. Anything else you guys have seen that works to bring out the colors?
