I know that the purple leaves can come from being cold outside. It hasn't frosted here yet but its been getting colder at night. My question is does that damage the bud or the quality or yeild? I am not worried about the leaves being a weird color, but i dont know if its haelthy. Because if purple leaves will mess up the plants, I might need to cut them down before it gets worse. Ill get some pix asap tho
