I have 3 seedlings about two weeks old, two are growing well, but one seems to being drying up and it's tips turning brown? This seems to spread downward until the whole leaf is dead, and it's really dry, I've tried misting but that doesn't seem to help. I don't see why it's only happening to one, can anybody help?

a little over watered and a medium root problem try to help root with a foliar spry. if mmman is right you need to repot soon with a different mix
