My first question would be:
Have the raised lesions spread to previously matured leaves or do they
only show up (as new lesions) on leaves that are just now maturing?
I'm not on the verge of confirming the diagnosis, I've never heard of
the term "Thailand Scab" before.

I have a few Catts with raised 'scabby' type lesions on the leaves. A local
grower suggested that it might be Thailand Scab. It seems to respond to
alcohol/cinnamon tea, insofar as the tea stops the spread on the plant. For
that reason, I thought I was correct in diagnosing some type of fungus.

Now I wonder. Thoughts, please?
