Another vote to ditch the weed'n'feed.
If you ever run out of ortho I've had good results with Bayer lawn weed and crabgrass killer. Most of these big box consumer brands are a weaker solution to what you can buy from a professional supplier, so don't worry about overdoing it (to a point).
Also, with most lawn safe weed killers you won't see results for a week or more, and it may require a second or even third dose.
