What's going on with my St Aug?

I put down bonus S weed and feed about a month and a half ago. About a week ago I sprayed some Spectracide weed and feed (2-4d) to kill some of the remaining clover. Did I burn it or is something else going on? It hasn't been hurting for water.

Looks to be gray leaf spot (fungal issue) LINK - in part caused by environmental conditions (rain, humidity, heat) and likely excessive use of nitrogenous fertilizer and some herbicide stress from the second spray.
I’d suggest you wean yourself away from weed & feed products, and stick with lawn fertilizers only and herbicides only, applied at the appropriate times and at appropriate treatment rates. .
ronk will be here with recommendations - he’s good with diagnosing lawn diseases and suggesting appropriate treatments.
Good close up photos by the way - that always helps with diagnosing lawn issues.

Will do, I've just been using what is easily available at the tractor supply. I'm new to this whole game.

What craw said. I would apply propiconizole. That usually takes care of a gray leaf spot.

I’m having the issue with blades yellowing in random spots but no gray leaf spot. Is it due to the excessive amount of rain we (Prairieville) have received lately? My yard tends to stay moist. I fertilized with Lesco 24-2-11 the day after Easter and have spot sprayed with Celsius. None of the yellowing has occurred in areas where I have spot sprayed though.
Eta: Nevermind, I just cant see well. I do have some gray spots when i take a closer look.

Got home and the gray spots have doubled in size. I have no doubt it's the gray spot you posted. It's also showed up in other parts of my yard that I didn't spray the spectracide. I ordered one of the chemicals listed on the ag center link you posted

Propiconizole is readily available. You could be spraying it right now.

HOw often do you spray? Got some of this and sprayed yesterday

Gray leaf spot isn't the toughest of fungus'. One treatment of propiconizole might do the trick. If not a follow up treatment 21-28 days later is needed.

There is a chance the yard had more weeds then appeared and when you put the weed killer down it killed more of your yard then expected. Give it a little time and see if the grass moves into those spots.
