You hope it's rust?! Not sure I understand that. Rust is not fun.

It looks like early rust to me.

Rust is cake to beat.

There is the easiest test in the world for Rust - walk through in white sneakers. If they're orange after a bit, it's Rust. Nothing else does that.

No orange residue on my sneakers. Here's a close up. Any suggestions?

This is spreading. Do I do nothing? Foliar iron? Urea? Serenade? Something else?

I’d get a standard fungicide. I don’t normally use fungicides often. But if it were me, in my location, I would deal with this now, while the grass may still have time to recover.

Welp. Did my math wrong and put down 24 oz of Spectator in 12 gallons of water over about 8K sqft. It was windy and getting dark with rain in the forecast. I needed to get it done. We will see what happens.
