How often do you foliar? And what was happening when you first noticed the damage? Did you keep spraying? Did you change ratios? I'm not an expert, but it looks to me like something externally applied has caused the leaf tissue damage. If this is an internal problem with the plant, wouldn't new growth show the damage as well?

After spraying for bugs, did you rinse the leaves?
