Pretty purple terps

I'm growing a strain that is known for purple terps (Barney's Farms Ayhuasca Purple) and have only gotten great quality green buds so far. What do you recommend doing to get the color to turn purple?

Terpenes only influence smell and taste, real purple strains turn purple without having to do anything to the plant. You might have to grow the entire pack to find the most colorful pheno. High quality light sources and cooler grow temperatures do bring out some color though, also stop feeding nitrogen earlier than other nutrients.

Plants that genetically turn purple do so because they produce more anthocyanins than normal plants that appear green.
A 2006 study in the Pakistan Journal of Nutrition found that anthocyanins in plants tend to die off when exposed to higher pH levels.

Hence, you’ll want to keep your pH levels neutral or slightly acidic for the best chances of seeing your plants turn blue/purple, in addition to cold.

I've read different opinions on what temperature is best. Right now I'm about 75 daytime and 55 night. I've also heard of people watering with cold water the last few days also.

7.0 is neutral pH and is too high

I am getting ready to pop some of Gu's Purple Mountain Majesty (a purple Goji cut crossed to a Stardawg male). Hoping for some coloring
