What’s wrong with my ZZ plant?

My zz is turning yellow and some of the leaves look like they have a darker spot on them. What could this be? I looked at the roots and they seem fine and I moved to a better draining soil, is there anything else I should do?
2ft to light, indirect
4” pot without drainage

Check for pests they are easily caught in big groups or vibrant colors
The area of growth may be a problem as well
