| Not being able to see the plant or the spots makes it impossible to diagnose the problem. Blind guesses about the problem or what to do won't help you very much. Also, I don't mean to be blunt, but your descriptions are somewhat confusing. First you say the spots were red but the leaves healthy then later you say they were brown and mushy. In one place you say the plant looked healthy and yet 3 weeks later it died? What happened between those times?
