I have some (alot) yellow spots on the leafs, all the leafs on 3 diffrent types.

Is this normal? What is it? and how to fix it.

Thanks

could be spider mites, have you looked at the bottom side of the leaf for critters

Didn't see anything the other day, when I moved them.
But i just took a look and It looks like the bastards are there. I'll be spraying tonight.
