Q.Hello! My cedron developed small “balls” in one leaf and I really don’t know what it is. My theory – the plant has an insect
and the plant is developing a defense against it. But I am new in this so I prefer to ask experts! Can you help me? Besides the little “balls” in one leaf, the amount of leaves that are developing holes or brown things. I think is important to see the whole picture so I will upload photos of both phenomenon. Pls, help me!

The plant looks more like lemon verbena than a tropical cedron tree. The small balls are probably leaf galls, abnormal growths caused by insects, mites, fungi, etc. Control is not necessary as they rarely affect plant health.
The brown edges could indicate lack of water. Be sure you are watering deeply when you water.
The holes may indicate a chewing insect so try a strong stream of water, horticultural soaps or neem oil to eradicate the pest.
