What's this??

My outdoor girls are getting this on some of their leaves.
Not real bad yet.
I'm spraying with pictured spray.

I saw evidence of leaf borer trails but the spots have me baffled.

Are you spraying during the day? I see something similar on my outdoor plants (not MJ) from direct sun after a rain or misting leaf foliar..and it dont effect all the eaves when it happens basically, the water droplets acts like a magnifying glass when sun hits it. I make sure now that I spray only at night. This is just a guess.

Thank you.
It's humid where I live and they have morning dew when the sun hits them.
That could be it!
