Corn has stripes on leaves - is it physiology or disease?

Corn (maize)    Moscow

Corn is grown at 25oC day and 12oC night, it rains every second days. What can be the cause of such symptoms? Physiology (some nutrients lack) and bacterial infection are suspected.

Alex, from the beaded appearance of the yellowing in the first and second images look similar to a magnesium deficiency. It can also cause reddening of the leaves that may be what you're seeing in the third image. Heres some more information about nutrient deficiencies in corn https://www.agry.purdue.edu/ext/soilf...
