I have a beautiful large Metallica palm that I got from a local nursery less than a month ago and I noticed the spots on a leaf or two shortly after buying it. But now it seems to be spreading and many of the leaves have spots popping up. They don't appear to be dying, per say, but the patches of spots are growing and there is some bleaching. Can anyone tell me what it is and if there's anything I can do to save it. I really love this thing and it wasn't exactly cheap, I'd hate to lose it.
