Purple on the leafs

Buddy "grower," the most obvious thing has to do with anthocyanins developing due to the cold (lower temperatures). Some strains at temperatures above 20 degrees (light hours) and 18 (dark) turn purple. It's not a problem; it's an attribute of their genetics and the presence of anthocyanins in their genetic makeup. Many friends who love to see pictures of purple buds would pay double for their "grows" to always come out purple in their phenotypes. The truth is that friends who buy purple and blue genetics to grow in the summer always end up with the greenest buds and leaves, impossible. But it often happens that in winter, many strains that shouldn't even turn purple end up coming out blue without any effort. This happens because of compounds like anthocyanins that react in the presence of lower temperatures. No worries... in the end, the terpenes, smoke quality, and bud quality are not affected by color, and you'll have a very good harvest, without the color costing you anything...
