Turning purple

My ww have turned purple especially on sugar leaves closer to harvest. What breeder were your seeds from? I had seedsman
 
Some plants just purple up in flower, it's in their genetic code to do so. Others are always purple and then there's the rest of them that have to have night Temps drop 15 degrees from ambient day Temps. Usually 60-65F night temps will give you secondary pigmentation
 
Anthocyanins. Some just "got it".

I still think that this is expressed more by temperature changing PH uptake by the plant. It expresses more when the temp drops more.

I tend to notice that my plants in the basement during spring and summer that grow in my basement will come out more "rainbow" than purple and will have a more hash like taste.

Then in winter time they will turn a hard dark purple and the taste is WOW!

Everything is run the same way I have done it for decades in 5 gallon DWC. Same mix, all is the same same, the only real difference is temperature variances between summer time temps and wintertime.

I've heard that also about the pH influencing factor.

Nite time must be 65 or less Mabe never look so Mabe that’s y I didn’t kno the exact number and yes
I turn fans off at nite as well wat else um humidity

Day temps are fine at 77F
Night is OK at 65, but you can go 60F.
RH in flower is always lower than in veg. 50-60% in veg and 35-45% in flower. Remember though, the drier the air is the more your plant will drink. If you don't adjust the strength of nutrient, you'll overfertilize very quickly.

Don't turn off your circulation fans at night. Plants still transpire and need the air movement to help shed water from the leaves. Just keep them on low or medium 24/7. Exhaust cycles remain the same.
