I live in Minnesota and put down Viroro Ultra Turf turf builder fertilizer with weed stop (30-0-4) at the recommended strength about two weeks ago. My wife, not realizing I had already fertilized, sprayed the entire lawn with Spectracide Weed & Feed Lawn Spray Concentrate about a week ago. My lawn in now turning kind of grey green/and brown in some places. I am thinking that it is way over fertilized and dying. Anything I can do to counter the effect! Will excessive watering help?

Excess watering may help if you have sufficient drainage. It would definitely help dilute the chemicals. If the damage isn't too bad it should recover on it's own.Otherwise you'll have to reseed at least the burnt spots.If there's a lot of dead I'd consider thatching and then aeration prior to seeding.

The high nitrogen content in the fertilizer is what is causing your lawn stress. When it comes to fertilizers, too much of a good thing isn't good. In fact it can burn and even kill the grass.
In your case it sounds like the over fertilizing stressed your lawn, but won't kill it. Just be sure to water it every day! Increasing the time a few minutes will help for the first couple of days to mix the fertilizer into the ground, once absorbed it won't burn the law.
The brown spots are probably where there was a high concentration of fertilizer. Once again water the affected area. The grass will eventually come back.
It sounds like your lawn needs water. I don't think you put enough on to kill the grass. The worse is yet to come when the lawn grows and grows and grows after a regular watering cycle. Once your lawn gets over the shock of getting too much nitrogen that is what it will do.
The grey/green areas sounds like not enough water. check the coverage of your sprinkler heads. They might be missing spots.
Your lawn is about to turn really green and grow like crazy.
Good Luck!!!

You could probably have a soil sample analyzed. Call your local garden centers/ nursery's until you find someone who knows where to get this done at.
You might then be able to add other nutrients to re-balance the soil composition. I would also recommend over-watering. This should help dilute the effects of the weed stop part of the problem. Weed products, in concentration can kill grass as well. This is why they do not recommend treating new or weak grass such as grass that is suffering the effects of a drought.

just water the bejeebies out of it and get your mower ready and you should be ok. when you think you watered a lot then water more. you should be ok.
