So what makes marijuana turn purple you ask? So we checked in with expert herb gardener Mel Thomas the author of Cannabis Cultivation: A Complete Grower’s Guide, 3rd Edition, published by Green Candy Press. Mel’s a world-renowned cannabis cultivator and at one time was the largest producer of marijuana in the UK. Here’s what he has to say, “Purple coloring in cannabis plants that have a genetic predisposition toward it is triggered by temperature changes in the fall. The green chlorophyll color usually masks any other colors, but tends to break down late in the season and a pigment known as anthocyanin begins to show through. For purple color to develop a strain must have the genetic potential to produce anthocyanin pigments. However, the color might never be shown if environmental conditions don’t cause the chlorophyll to breakdown. Kush strains tend to develop purple coloration when subjected to low night temperatures during the end of their life cycles and plants with heavy traits of the Hindu Kush plant, produce some of the darkest tones found in any marijuana strain. Nitrogen will not induce color change, unless you over fertilize and they go crispy brown!”
