About two weeks ago I did a 95% water change, and made the mistake of first filling up the tank with tap water and then adding the water conditioner (Seachem Prime), rather than first adding Prime to the tank. I don't have fish, and I thought that this would be OK for the plants. Well, it wasn't and most of my plants experienced some degree of melting, except for the Java fern. About a week later I started EI dosing with dry ferts. All the plants have started growing new leaves since then, but the new leaves on the crypts (wendtii Green and Tropica) are dying. What could be the problem?
