Thinking it could be sunburn, the light isn't that close to the monstera but I've left I on for 12 hrs a few too many days and the yellowed leaves appear closer to the monstera as opposed to lowest down.
I'm also due for a repot, it's probably pretty rootbound right now.
Any insight appreciated! Thanks!

This isn’t sunburn.
The substrate looks questionable (not sure what it is) but I’m pretty sure you have root damage.

Also not sure what the debris on the leaves are. Could be pests, could be dust(?)
Check the roots, burn in a leaf below the larger and higher ones is very unlikely.
Monsteras need a very chunky mix that lets in more oxygen than pressed soil can. The substrate doesn’t look well in the picture, take the root ball out and untangle everything, check the damage and put it in a better mix. Only water when most of the pot dried out. Otherwise excess moisture will suffocate the roots and they will rot.
It’s most definitely not a root health issue as that wouldn’t present anything like this. If the damaged areas were concentrated near the light, I would suspect a burn based on the appearance. I am the great thrips identifier and I’m not really suspecting that here. 💚
