Burnt edges?

On one of my VFT's several of the leaves edges are blackening
. I was wondering if anybody knew what would cause this? It doesn't get too much direct sunlight maybe 5 hours a day, which is about perfect. I always use distilled water, and the humidity and temp are about perfect, and the soil mixture is also right, anything else that would cause this?


It's been one of dem days
Could just be older leaves dying. I have several VFT that have leaves turning black along the edge. As long as the new growth coming up in the center of the plant is healthy, I wouldn't worry.
old leave sis all I can think of

I have herd about people having to change the moss in the pot
