Hey I have an outdoor indica clone going right now. And I started to notive the stems of the side leafs starting to turn a purple sort of pink color, I kept my eye on it and as time went by I'm not noticing the stem is starting to turn that same purple pink ish color. I'm wondering if thats a problem or could it maybe be a purple strain?? Please any answers would awesome! I'm not sure if I should be getting worried or really excited!
