Can anyone tell me what this problem may be and or a possible solution? Transparent blotches appearing on AG leaves and spreading fast. Have pics in growers diaries under 'Lookajook' if someone has the time to check. Thanks in advance.

Any white powdery residue on the upper leaves. What you have looks like what powdery mildew does. Although I did not see any mildew in your pics. I am fighting it now with a copper hydroxide solution and immunox.
