I have to agree.

Is the newest growth discolored as well? Leaves touching soil is never good. Invites molds, funguses, viruses etc. Not saying those are the problem as they are not.

I am very careful when it comes to watering. I even lift leaves so i dont splash anything on them. Then i double check to look for water any where on leaves. The top new growth is fine. Its just the bottom main fan leaves
