My plant's leaves are turning black, any ideas on what might of caused this and what solution might help? Currently the buds all look fine to me, it's just the leaves. All of the pistols on the plant's buds are orange for the most part, don't have a 100x microscope or better to verify color of trichomes for percentage of see through white, milky white, and amber orange. Plant never drooped down or wilted so hard to say if it could of been due to over or under watering. I think it may be a copper deficiency but I may be wrong, any help greatly appreciated!
