If I dont kill all the weeds, but throw down fert, am I helping the weeds? I sprayed them, but if they are slowly dying, I dont want to help them by giving them some N. However, my grass needs some N
You're fine to apply some N. Believe it or not some herbicides actually work better on some weeds when used in conjunction with nitrogen - Katana plus Urea on annual bluegrass comes to mind.

Just making sure but I can apply Certainty in any temp? Like even if I'm going to be hitting mid 90s?
Any of the products in the Bermuda Triangle are safe in any temperature. I believe that was part of the reasoning behind choosing them.
 
Lord have mercy, the nutsedge is starting to emerge. I'm thinking of the hose attachment image to get rid of it. I used the image on my back yard for some poa locations and they are all yellow and dying now. Obviously Sedgehammer is probably best, but price difference is huge. Thoughts?
 
Dismiss works well for sedges as well, especially kyllinga but it definitely has a temperature limit. @mjh648, not sure which part of the label you are referring to but I know they say not to use a surfactant in higher temperatures (Celsius).
 
I have used Certainty, Sedgehammer, and Image and all worked well to get rid of the visible sedge. You won't really ever kill it for good but each of those made what I had disappear for a while. I use the Celsius and Certainty along with a little bit of surfactant pretty much year round. The few months of real winter and dormancy I see very few weeds pop up and during those months I use Round Up concentrate and mix a half gallon for spot spray. The C&C combo I use with any temp. You will see a yellowing at times but the grass does not die. The only "bad part" is the cost to get setup with the ingredients.

My Celsius and Certainty are enroute. Admittedly, I have not read the labels, but is there a established mix for spot treatments when mixing the two?
@Triplesticks

Make sure to mix with a non-ionic surfactant for best results.

Something like this: https://www.tractorsupply.com/tsc/product/farmworks-80-20-surfactant-1-gal
I bought this https://www.amazon.com/gp/aw/d/B004XDHRCE?psc=1&ref=ppx_pop_mob_b_asin_title

Am I good to go?

@TNTurf have you tried pennant magnum?
I haven't. The 3 ingredients listed in the triangle have worked the last few years and its a big initial investment to get the supplies so I have stuck with the formula. I would be willing to try other options but only after I need to resupply.

I usually mix at the medium rate for spot treatments since I tend to "spray angry" when spot spraying. You may want to do the low rate if you are mixing both Celsius and Certainty.
I mix at the full rate and do a quick pass over the spot. Even then, I will see a bit of a yellowing in the spot for a few days before it returns to normal.
