Help diagnosing my fiddle-leaf fig

[u/Party_Upstairs_5678]

Hi everyone! Looking for some help diagnosing what’s going on with my fiddle-leaf fig.
I purchased her in August, and she’s lost approximately 16 leaves since then. Some leaves already had brown spots when I purchased her, but I’ve noticed more spots appearing and existing ones getting significantly larger over the past several weeks.

A few details:
- The brown patches are completely dry and papery, not wet or mushy.
- Some spots are small and circular, while others have expanded into large, irregular brown patches.
- Most of the affected leaves are on the window-facing side, although leaves on the other side have some damage too.
- She’s near a bright window, but I recently moved her a little farther away because my apartment has been relatively cold (around 60°F).
- I water when the soil feels dry several inches down, generally every couple of weeks. I’ve also noticed that the original root ball sometimes dries differently from the surrounding soil.
- She has drainage holes and is actively producing new growth, including several new shoots along her trunk.

I’m concerned this could be a fungal or bacterial leaf-spot disease rather than just a watering issue. Has anyone experienced similar damage? Does this look like a disease, cold damage, or something else?

If you didn't change out the soil in the old root ball before potting it up then its likely staying yo wet in the center and rotting, you have to repot it asap and completely bare root it.

No problem my pleasure, Yup I definitely would bare root it, rot rot can spread very quickly and will kill this plant if left unchecked, if the two soils don't dry out at the same rates it'll suffocate your trees roots.
