Save my sea grape

I’ve been growing a pre-bonsai sea grape for about a year and a half with success. Just recently I started seeing red spots and zero growth. I tried re-potting the guy and his roots look great, but the red spots are continuing to spread. Does anyone have an idea about what this is?

Hi, I thought they did go a purple red colour but that does look a bit weird with that spot. If it was mine I wouldn’t be worrying.

no experience with the species. But has some fungal pattern imo, so would then treat with some broad spectrum fungicide if it spreads

BUT: If i look at the picture your hand is completely purple also (which is why i did not recognise it in the beginning). So i assume what we see on the picture is not as it presents in actuality.

Ive only ever seen seagrapes in the wild. Know NOTHING about the type.
.
However, the fingerprint pattern appears to be a leafminer?
Fleshy leaf.
Can these take a systemic? bug killer?

You know, I was actually not all that worried at first and then I watched the stream about nematodes and suddenly everything looks like a borer to me. Also, there are some purple lights in the greenhouse for younger plants, but I can assure you that dark purple is very close to the real color. I’m going to try hitting it with some copper based fungicide and see if that does trick.
