Yellowing leaves can be due to watering issues; to much or to little.
They can also indicate insects or disease.

I see some evidence of leaf damage in this image, but quite difficult to diagnose an exact cause.

Check the soil and make sure your tree is adequately watered and not to wet.

Neem Oil is a good and safe treatment. Neem Oil is organic and works both as an insecticide and fungicide. It is safe for people and pets.

Treat the plant and be sure to hit both top and bottoms of the leaves.

You can retreat once a week and watch to see if the plant improves.
