My girlfriend boight this thai monstera a month or so ago and until now its been fine
Notified at the start of the week two leaves had what looked like started rotting, they are not crispy brown but soft brown. She said shes noticed it slowly spreading over the last few weeks.
I went to repot it and check for root rot and while it wasnt rotting the soil was still damp, so i removed as much of thay as I coukd and added some dry soil. We bought it in houseplant soil with vermaculite but whej adding dry i only had some leftover seed compost. The plan is to not keep that but my main concern was removing the still wet soil
The pot has drainage, and it was being watered when the soil at the top felt dry. I have a feeling it may have been watered a bit to often as we have a normal monstera too that drinks a lot more
A houseplant fertiliser was used once but no other plants have any issue (inc the other monstera)
We live in Scotland and it sits near to a north facing window (living room). Currently it'd by the south facing window as it gets a BIT more light there.
During this it has put out another leaf (pictured) which is fine

Consider changing the soil so that it is chunkier and easier to drain, also check for thrips (little black bugs)
The roots don’t need to be rotting for the foliage to have damage related to the soil staying moist for too long.
Vermiculite is an additive that helps retain moisture. You want soil that has more added perlite in order to increase drainage.
