I have a plant from bag seed planted in the ground; end of second week of flowering the leaves are turning a purple color ...any body know if this is a problem or a strain?
A chemical known as anthocyane resides within the Marijuana plant. It is released when the plant is getting cold, kinda like a anti-freeze. In most cases you have nothing to worry about.
hmm what the above poster said Is new to me, I was also under the impression it was P lockout from cold. But this now has me thinking why various plants purple more in cold. perhaps higher amounts of this chemical.Cold locks out P intake and there for you get purpling . It can all so be a P deff or just the strain. They will purple at the end of flower as available P is used up too.
