I come from the tropical and temperate climate of Southeast Asia. I have a lovely Ficus Religiosa that sprouted in a small pot on my balcony naturally at about March this year. I transplanted it to a bigger pot using a rich potting soil mix shortly after, and the tree has grown much in the months ever since.
Recently, its come under attack from some disease which I cannot really identify. Attached here is a photo taken directly from my tree.
From my research, it looks like a sort of leaf blotch disease, but the underlying pathogen might be different. Furthermore, the paper I've referenced doesn't seem to give much practical advice on a treatment plan. The treatement routine might be non-trivial, as it requires removing dead leaves to prevent spreading of the pathogen.
