Ask a Question forum: Light brown spots on my Monstera

I'm really new to gardening and recently there's been a few brown spots that started appearing on my Monstera leaves. I've been searching the internet but have not come across any articles/forum posts that looks similar to this. They can be scraped off using fingernail/toothbrush but it's really cumbersome as they are quite stubborn. I was wondering if anyone can point me in the right direction for a cure to this problem? My leaves have been turning yellow due to this.

It looks like scale. Use a Q-tip dipped in alcohol or some alcohol wipes and wipe them away. You will have to watch and get them as they pop up.

The scale insects are not creating the holes and they are probably not causing the leaves to yellow at this point.

Mix a solution of 5 parts water, 1 part alcohol and a squirt of liquid soap. Drench spray all leaf and stem surfaces so that you make direct contact with even the juveniles scales that you cannot see. Thoroughness of coverage is the key to successful treatment

Pests often appear on plants that are under stress for other reasons, such as improper light or watering. That may also explain the other symptoms you are seeing.
