Mulberry tree disease

Question

I have a small mulberry tree in a pot. It has been doing fine, but in the last two days about a quarter of the leaves developed a problem. The tips and edges of those leaves look like they got fried or freeze-dried. They’re completely dry and brittle, and you can crumble them like dry autumn leaves, but the center and bottom of the leaf is normal. Also, the dry brittle parts are still green, not discolored at all, no yellow or brown areas, no spots, no mold, etc. Any idea what is wrong with it and how I can save it? Thank you!
