Camellia Leaves Turn Brown In Middle – Not Due To Sun

Question

All my camellias, young and old, suddenly developed a light brown along the central vein. Some of them have been in place for decades, and never had this problem. There has been no change to sun exposure. What causes it and how can I fix it please?
