Purple stems and stalk?

Hey whats up?
I have an indoor thing and my blue cheese has purple stems and the main stalk is also purple? What Problem is this and whats the cure? Please
Thanx, Sinthia

Whats an indoor "thing" lol JP. But purple stems usually mean a deficeincy in nutrients. Pics always help.

i find that cold temps at night can turn stems purple, if its not that then some strains do show purple anyways, i did blue cheese and my stems were purp. if ya foliage is fine and u gettin new growth dont worry bout it gd luck wat set up u got there

cold temperatures, lower humidity and genetics also cause purple stems
