Well just two of them. I've got two Brazilian Sword Med.(White sail houseplant) I noticed the other day that some of their leaves were turning yellow. I took a closer look and I noticed that the stems are turning black at the base. I'm at a loss as to what this is or what to do. I don't have fish in the tank and none of my other plants are showing any signs of disease. Any ideas what this might be? I really don't want this to spread.
