Q.Swiss cheese plant
I have a Swiss cheese plant that has a couple of leaves that are turning brown on the edges. What could be causing this? It is in a pot in a well lit room away from heat and droughts.
It sounds like either a not enough light problem or root rot. Move it to a location with more light and check for root rot. This article will help you with that: https://www.gardeningknowhow.com/plant-problems/disease/treating-root-rot-gardening-tips-for-housplants.htm
Just for good measure, give it a bit of fertilizer.
Also water the plant with distilled water or leave the water to sit for 48 hours before using.
