So Iv seen a few strains that have colors like pink, red, dark black, and was wondering if there are strains that always have those colors, or is it all chance, or something special you have to do, or?
It has to do with a few factors can cause color morphing. Some will naturally turn colors. Others they tend to at end when plant is fading and starving as it ripens. Cold roots can bring color out, but not my preferred method if I find a plant that wants to go out pretty.
There are many users far more experienced than me, but I believe it has to do with dark periods being consistently significantly (10 degrees) cooler than day temperature.
