Brown And Yellow Spots On Calathea

Hello, these spots have formed on several of the leaves of my calathea. Also some leaves have started crisping on the edges. I’ve looked it up and it could be because 1. I fertilized right after transferring the plant to new soil that probably had fertilizer in it, so I could have over-fertilized and 2. the tap water in Berlin is very hard, and maybe I need to change to filtered or rain water. Also the plant receives no direct sunlight, so that’s not an issue. I love this plant very much and am sad and scared!
