Translucent spots on basil

[Luzbug]

Hi folks, I'm just new here so sorry if I'm in the wrong forum... I have a big planter or very healthy basil, but the top leaves are showing small (+-1mm) transparent sspots. Can't see any sign of beasties, and they are always watered at ground level so splashback seems unlikely. Any idea what might be causing this, and how ttofix it?

Hello Luzbug welcome to the forum! Is there tiny insects under any of the leaves,extremely tiny that you can't see them move? I can see little black dots on the leaves do you know what that is? There's also insects that are leaf coloured so they're camouflaged. It looks like insect damage,are the plants inside or outside?
