How can I make an Existing lawn flourish?

How I want my lawn I want a beautiful lawn with no weeds and a brighter healthier green. Right now there is a few weeds and the grass just isn’t as lush as it could be, it just doesn’t compare to my neighbor's.

Location/Original Characteristics The lawn that I want to make flourish is located in Flandreau, SD. The lawn is about 500 square feet in size The current grass type is a mix of blue grass, ryegrass, and fescue The grass has available irrigation in all areas The turf has heavy traffic

Soil Characteristics The soil characteristics are as follows –Moderately coarse soil texture –6.7 pH –10 –14inch deep soil depth –The area is flat

Maintenance I would have to –Water once a week or as needed –Mow when grass reaches 3 to 3 ½ in. –Fertilize in May, June, July, and September

Fertilizer Scott’s Turf Builder with Halts Crabgrass would be applied in May Then Scott’s Turf Builder with Plus 2 Weed Control in June In July I would use Scott’s Turf Builder with Summer Guard Then in September Scott’s Turf Builder with Winterizer

Irrigation There is already a sprinkler system I’m going to water the lawn once a week or as needed

Conclusion I wanted a lawn that would compare to my neighbors, it lacked the luster of their lush lawns. I believe it needed nutrients and water, and will be nice looking late this summer, and for sure next year.
