I have a phal with 4 leaves. One is in the process of growing. The oldest and significantly largest leaf has some burn on it and some strange bumps. This has not affected any of the other leaves. The reason the other leaves are smaller is because the plant went through root rot and is recovering, so the leaves are growing smaller. The oldest leaf is ugly due to the burn (oops, my fault...) but has shown no signs of wanting to drop off. Should I remove it? Will it help the other leaves grow bigger or will that make it worse?
