I've got these much lighter patches all over my yard. I'm new to this and all this grass was over seeded last fall. At that time I got what I'm 99% sure was lawn rust, about everywhere. The entire yard was primarily weeds before the overseeding. Still got weeds especially grassy ones but there is more grass.

I'm not sure what I'm looking at here whether this is a kind of fungus or what is causing all the lighter yellow spots throughout the yard. It's pretty much everywhere.

It has rained a lot this spring, I have not watered this. I put down prodiamine end of March, some N in April, have spot sprayed a few times with tenacity+triclopyr. Any insight would be great!
