Beginner Gardening: Help please: Black rotting spots on my Bodhi tree leaves! , 1 by PatrickA_FL

Here's the photo of the older leaf. Should these be removed? I don't have but one new 3" leaf and a few 1/2" leaves that do not look similar to this. I fear if I remove the bulk of the foliage it will die. Does anyone know if this is true? If not, perhaps I should remove all of the foliage to hopefully rid whatever is causing this?

FYI, I have applied a BT drench (Mosquito Dunks) to the soil and have recently fertilized with the 3-1-2 Miracle Grow which I think is what spurred the leaf growth.

Please help me help my tree.

Thanks again,

Pat
