Any idea if this happening to my leaves because of a deficiency or pest?

Hey guys, I fed plants last night and today this has been showing up on lower fan leaves and a couple middle ones. Not sure if it's cal mag, but I do supplement it in my feeding. Any help?

Check for bugs. Calcium shows up as spots in newer leaves as it is a mobile nutrient and magnesium older leaves as striping between the leaf veins as it is immobile.

is it just on some of the old fan leaves or is it on new leaves too?

Yeah its only happening on lower and older leaves. The new ones ate growing fine. Could this be magnesium? Since it isn primarily in between the veins. Here is an updated picture

ok, could be..
early signs of leaf septoria, it’s an outdoor plant? well it’s been very high humidity this year outside. might want to look it up and see if that helps..
i think it is..
maybe others know..
i doubt its pests..

No that doesnt look like mag deficiency.

Do you think it could be thrips?

Dont know. I would be scoping under and on top of those leaves. Unless it is obvious in the pics we are all guessing from here. ;-)
