So the spectraside I have in the hose end sprayer says 85 and the hand held spray bottle I have says 90 so I don’t know what to think lol. Both are the yellow top 24D.
I probably need to start with a soil test. And what about thatch...is that a issue of mine too?
My front is worse with these areas that are think like this. Not real green. Some spots look good and green. Last thing I did was Scott’s max green about 2 months ago. I was going to try to spray weeds and put down some more fert.
I dug my finger into this one

Well why take a chance, 2,4D is known to damage desirable turf at high temperature, save it for fall or late winter use. MSM Turf and Celsius have a higher temperature leeway for use - consider those, just be aware that most post-emergent herbicides have have a higher probably of damaging, or temporarily stunting desirable turf grasses at high temperatures.
Your St Augustine lawn looks chlorotic, and those patches of dead grass suggest you might have/had lawn disease issue. I’m not comfortable in my knowledge of lawn diseases so if ronk sees your post perhaps he can provide some thoughts and advice. If your lawn is under stress because of a disease related issue, I might not use a herbicide in that area of the lawn for the time being. I don’t see any significant weed issue in the photos you posted.
Thatch - dig up a divot or 2 from the yard to see how thick the thatch layer is. LINK If your lawn is compacted perhaps core aeration would be more desirable than a dethatching process. LINK
Soil analysis for base line info is always a good idea.
You are probably due for a another lawn fertilization if done a couple months back with Scott’s - which I think is usually a fast release product.
