The purple color is caused by pigments known as anthocyanins. These pigments are found in many plants. They are responsible for the purple, blue, and red colors in some strains of weed. They protect against UV radiation and help regulate plant temperature.

Sometimes genetic predisposition, sometimes cold temps, and sometimes from too much phosphorous. I picked a nice green stem strain and a blushy stem strain for my grow, with the notion that I would always be able to tell them apart in the garden. Then the weather got cold and all the leaves on both turned purplish with blushy stems and I couldn't tell them apart until I flipped them.
