Turn the leaf over and look for the tiny bugs.

No cant see out and im in aeroponics so i asumed i wouldn't have a problem with bugs, its only on a couple leaves and not every plant, cant see out similar in the forums and book, everything looks great apart from that and a few tips showing yellow with the nutes.
