I'm starting to notice that all of my fan leaves stalks are turning purple. and some of the hairs on my newly forming buds are developing purple tips could this mean a purple strain of bud? let me know what if it is or it is something else.
From my experience and what i've read the purple color comes from the weather getting cooler at night. Or maybe you do have some purple in your strain. Wouldn't worry about it as long as the rest of the plant looks healthy. My indoor indys always get the purple tips, kinda cool!
