Judging from position- and size of leaf: old age !!
Leaves have a life-time. They are produced - doing their photosynthetic work - grow old - and die. Life-time of leaf is different from species to species, and influenced by a lot of environmental issues. Strong changes in environment will often hit older leaves harder, causing dead.
Basis is, though, that any leaf will die of old age at some time.....and this is not due to poor flow, mal-nutrition or other "dis-orders" - it's natural !!

.........so if not a lot of leaves follow this, in your case I would not be worried about these (two?) leaves dying.

Allways remove dead leaves, if possible.
