I have read a lot online that seems to agree with the notion that in strains where purple/blue/red buds are available that to get them to display requires colder temperatures. I have also read that this is technically a deficiency in the plant as it limits its ability to utilize phosphorus (which to my understanding is a fundamental nutrient; especially in flowering). Other sources still state that cannabis plants that have more purple/red/blue tints have more terpenes and research is beginning to show that the terpene profile can have a substantial effect on the high the buds produce.

Can anyone here help me weed out the true statements in what ive just said and which ones are pseudoscience? I currently have my plants at about 62-68 during the day and 54-60 at night. The strain is Liberty Haze by Barneys Farm. The picture attached is from a few days ago. Im currently halfway through week 4 of flowering.

I'd like to help you, but how are us mere mortals to know for sure?

I THINK that purple has no bearing on terps.

I think that purple can be brought out of any genetics which has anthocyanins as part of the makeup given appropriate inputs. That's most weed. UVA lights will turn plants purple too - which I am 99.99% sure is anthocyanin production and does nothing for the plant except bag appeal.

Yep UVA will bring it out but it has to be present in the plants genetics. And it’s just color and nothing more. From what I have seen in my grows anyway.

Bring your daytime temperatures up. They don't have to be low to get a cold-triggered color change. Just let it drop into the 50s at night, if possible.

In my experience, strains that produce colorful buds without being triggered by cold definitely have a similarity in flavor and scent. I can't tell you if it's a terp or something else in the plant that gives me the scent and flavor.

When the colors are triggered by cold, there is no influence on scent or taste, that I can detect.

While I love pictures of colorful buds, I couldn't care less if my plants are colorful or not. It's meaningless for what matters. In fact, when I grow strains with both a green and colorful bud pheno (not cold triggered, but produces colorful buds, no matter what), the green pheno is invariably more potent, or at least feels more potent, than the colorful one.

Hahaha! Of course I only expect advise from mere mortals. Thanks for the tip on UVA lights by the way. Ive avoided them thus far becuase I dont want to possibly damage my eyesight. But ill keep that in mind.

How much higher would you say the daytime temp should be without making the temp differential too much to where it shocks the plant?

I don't know what temperature change would shock the plant. I had a grow that regularly went from 80 during lights on to 50 during lights off, and they weren't shocked. I like high 70s to about 85.
