Dried out, necrotic leaf tissue


The oldest leaves showing the worst damage and the youngest leaves showing no damage are clues that the cause of the dried out, necrotic leaf tissue likely happened several days before the picture was taken. The lack of leaf discoloration indicates that it is probably not a nutrient deficiency. The bare soil surface was susceptible to movement by strong winds occurring the week before, abrading exposed leaf tissue and causing the windburn evident here.
