Tiny white spots on leaves

Hello! I have my plants growing outdoors. They look pretty healthy to me, but I have noticed that the leaves are displaying tiny white spots. The spots seem to be accumulating mostly on the lower leaves. I thought initially they might be spider mites, but thought I’d see what people around here think.

looks like there might be a tiny white fly or an aphid on one of the leaves in the first picture when you zoom in

I would recommend checking the underside of the leafs for pests first. Might be something munching down on your crop.

I’m with @Jmesser80 get your loop or pocket scope and look close under and on top
mites ???

Thanks for the input! I pulled out a magnifying glass and looked closely for any bugs, but didn’t see anything obvious. I still sprayed the plants down with some Captain Jacks to be sure and I haven’t noticed any new leaves with these spots popping up.

However, now a few of my plants have leaves with yellow spots :confused: Looks like septoria to my novice eye. What’s the best way to take care of this, other than removing the affected leaves?
