ThankyouLooks like an old necrotic spot that just lost the dead material in the crater. Started very tiny and just got bigger as the leaf grew out. Just keep an eye on the whole plant.
That’s interesting that it’s on newer growth. My first thought was bug problem. Interesting. Can you take pics of the whole plant without the lights on?
