black leafs, not healthy...

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

that is the first thing I read, too. This plant is not healthy looking at all, can sadly guarantee it won't live the week if nothing happens. It was under the light all day, and she's still drooping to the stalk. The black is spreading pretty bad to another plant, it's going to start there too.. I'll get a picture if you need it


edit; I can't get a picture.. I do not have access to a camera right now. Desperately need this resolved..
