Fiddle leaf fig is being fiddly

Hello!

I'm having trouble with my fiddle leaf fig that I purchased about a month ago. It was full of leaves when purchased but has been steadily dropping leaves since I repotted it at my apartment. I have it in a larger pot and used orchid mix for potting soil. I water it every 7-10 days. I recently (1 week ago) drilled holes in the bottom of the pot to ensure proper drainage, and some water came out after drilling. I attempted to break up the root mass when repotting but was largely unsuccessful. The browning leaves started at the base and seem to be working their way up the plant. I did a plant feeding a few weeks ago.

It gets a good bit of indirect light, and including pictures of where it sits relative to my south facing windows for context (only have south facing windows in this room).

Thanks for your help!
