Yes too much water can turn leaf into yellow very quickly
Yes Always maintain the moisture. Observe 2/3 more days …if more leaves turn yellow you have to repot.often plant reduces excess moisture through this symptoms. If you are giving water in right quantity …but the base of root is stacked so they will hold more water. Please check after 10 days … and repot. And there is no nutrition problem in my opinion because it’s others leaves are so much healthier.
