There's nothing wrong with this plant. The few yellowing leaves on a couple leaves on the very lowest part are a typical reaction to transplanting. Even the most gentle transplant stresses a plant and even a small shifting of the soil around the roots tears the little micro hairs that cover the roots, usually resulting in the loss of a few lower leaves at most. This doesn't hurt anything.
If you have nutrient problems or other serious stuff the tips of your leaves will tell you first. Your leaf tips are good and indicate, for now, things are in balance.
