I am not an expert, so you might want to hold out for someone who knows a bit more, but I think it may just be sun burnt. It looks like you still have at least one healthy leaf on each plant, correct? You can either wait for the unhealthy leaf to fall off or cut it off with a sterilized razor. Roots look okay. Just give them a little water and indirect sunlight and they should be happy soon enough. :-)

It does look like sunburn, but your plant does not appear healthy. Do you have a picture of the whole plant? The roots look dehydrated and you might have some scale or mealies.

We need more info on how you are growing the plant (light, water, temps and where you live) and a picture of the whole plant showing the roots.
