12.5 percent seems high for a known fatal condition among photosynthetic species.

I very rarely see that. Because it happened to two different species at
the same time, I would suspect some unusual environmental condition.
Maybe a unintentional chemical treatment or irradiation of some kind.
Live in an industrial area or have a cell tower above your house?
(mostly joking, lol)
