Hello, first time grower here, my tobacco has finished air drying after 7 days towel curing. Some of the leaves have these large brown spots that developed near the end of towel curing, and they look different from other leaf issues I have seen posted. When the leaves still had moisture the spots had a stronger sweeter fermented tobacco smell compared to the leaves that wre fully yellow. A couple of the leaves had white fuzzy mold on the a couple of the brown spots and wre discarded, but the rest have fully dried without any signs of mold.

Wondering if anyone has any insight into what caused it and if it is harmful or harmless? Thanks in advance
