The leaves will first turn yellow and then drop off.
Healthy leaves will have no marks or whatsoever.
I recommend removing any "dirty" leaves right away.
Usually that's the end of it. If you leave them on, you will see this again and again.
Even after you remove the affected leaves, keep an eye on the plant as the disease often returns.
Other than that, these are usually fuss free easy strong plants to take care of.

Thank you NY! I was hoping you would respond since I consider you a dendro expert. I sent the vendor pictures and he said it was perfectly normal senescence. It disappoints me that he wasn't honest. I suspected disease since that had previously trimmed one of the bad leaves.
Would you treat it with fungicide?
