I have recently repotted my fiddle leaf fig tree. I was suspecting a root rot so I repotted the tree into a more draining mix. Surprisingly, there was no root rot when I pulled the tree out, despite some funky smell when watering it for a few weeks before repotting. Anyway, after the repotting the tree was ok for a few weeks and then suddenly started dropping leaves. It's dropping about 3-4 leaves a day and some of the leaves that are still on the tree have weird black spots and yellowing. Even if the tree can't be saved now, I'd like to know what I did wrong and what's killing it. Any help is much appreciated! :(

Here's some of the pictures (on the second picture theres some dried leaf damage near the stem - that was there for ages and is not related, but the black spots and yellowing are all related):
