How much experience do you have diagnosing plant problems...? If you have none, might be best to fill-out the troubleshooting form as best you can, (link is in my signature) and provide a picture if possible. We might find something you overlooked.

It would be irresponsible of us to diagnose blindly and risk further plant damage.
