Q.What Is Destroying These Sapote Leaves?
three sapote seedlings (grown from seed for fun). The biggest seems perfectly fine. The two smaller ones have this condition where the green leaf appears to be eaten away, top and bottom. Have looked at it with a loupe and don’t see any insects. It is inside, in a south window. Putting it outside is not an option. Could someone tell me what is causing it, and whether I should treat it or destroy the plant. Thank you!

This looks to be a fungal infection. This happens from saturated soils, or soils that do not have a chance to dry out down to about 2 or 3 inches, very thoroughly, between watering.
I would treat with a fungicide, and make sure to let the soil dry out between waterings. Here are some articles that will help:
