What Is The Cause Of Brown Spots On My Seedlings?

I am growing sugar apple seedlings, they are about 3 months old. I noticed recently that some of them started developing brown or yellow spots on the leaves? What is that? One of the seedlings ended up with dried leaves. Is it caused by fungus? Or insects?

Most likely too much water. Try cutting back on the water, let the soil dry before watering again. Increase air circulation such as with a fan, and provide bright, indirect light.
