Is my plant ok? (pics)

Just woken up to find a leaf has gone all white n crusty /shrivelled? Is my plant ok? Thanks sorry about pic quality but should give you an idea of what I mean

The cotydelons (or however you spell it) will naturally go bye bye.

OK thanks but is that normal at this stage or does it happen whenever regardless just the white shit on it I'm curious about

As for me it looks fine.
