it looks like necrosis from something and if so needs to be flushed..
i think spider mites would have more visible pitting leaf damage
still looks like too much fertilizer ....
can you look under one of the leaves with a lens of some kind?
......and watch the other ones
that plant does not look good

Last pic, towards the lower right corner...is that a larvae of some sort I see in that taco leaf?
>>>it almost does..thrips are that size too..but they would not make that leaf grow strange
distorting leaf growth sounds like
russet/broad mites ...they do things almost similar. to leaves
.but you would not be able to see
them or the larvae..they are way too small
