Here's why I think it's light burn...

Or heat stress...

Keep an eye on it, maybe move it to a different spot (if you haven't already) and see if it gets worse. I don't think it'll get better, but if it stays the same then nothing to worry about.
to me it deff. looks more like the leaves in the first pic you posted. i moved the plants around a bit but i have been having problems with heat.
Ive had two plants with leaves curling up like canoes but nothing too bad to where the leaves get crusty and change colors.
the plant in question has never had curling leaves or anything like that so idk,

i guess ill just keep and eye on it and if i notice anything more ill let you know:thumbsup:
