bumps on my phal leaves

[brit6v]

Hi everyone,
I unfortunately had my first experience with a crown rotted Phal several wks. ago. About 2 wks. ago I had given up and was on my way to the dumpster to put it out of it's misery when I noticed 2 basal keikis. They have grown fine and looked very healthy since then. As I was inspecting them this morn., I saw that the leaves had developed some bumps/worts that I haven't noticed before today. These bumpy areas are on both the top surface and underneath the leaves. The Mother plant had them as well...but I only saw 3 under 1 of her 2 leaves. The bumps were raised and hard and would not come off without plant tissue coming off also. In one of my pictures, you may be albe to see a bump on the edge of a keiki leaf that I scratched with my fingernail. I have had scale problems in the past, but these are not scale.

I would appreciate it if you would give me your opinion of these and also advise me.
