This is for my own lawn.
We use Cool Power, or 4 speed on all of our fescue lawns in middle TN in late fall and early spring, after the second mowing of the new seeded grass. They will smoke all of your cool season weeds. I would do a blanket spray of the entire lawn, you can't always see newly emerged weeds when spot spraying. Save your Tenacity to spot spray crabgrass next year.
