headshake Reviewed by headshake on . black leafs.. not lookin good I have a plant that's showing a very bad case of this, I don't know what it is. It's leafs are turning black, and it's drooping like hell. Leafs feel healthy aside from the look.. A few others are starting to show black on their leafs ... getting worried :( Rating: 5
