Thanks...I will digest all of this nitrogen information.

I've looked everywhere on the net I could find that has photos of lawn
diseases. None of the pictures look like what I have. Mine isn't
patchy or blotchy, and the green blades themselves never look like
anything is "attacking" them...they seem healthy and green.

I've already done the Scotts pre-emergent (Halts with Turf Builder).

I used two 40 pound bags, which are supposed to cover 15,000 sq ft
each. I ran out with only the small back corner undone.
I used a Scotts Brand spreader set to their recommended settings.

So, I can't be sure that this MEANS my lawn is a little over 30,000 sq
ft....I will figure out a way to measure and calibrate as you
mentioned.

Yes to me your lawn didn't seem diseased. Normally diseased lawns are either
overfed or overwatered or both. To me it looked more like it was
undernourished.

Good lawns can take time to develop. I've just finished an 11 year stint in
the business and I always found it frustrating that new customers would want
a great lawn right away. If you concentrate on nourishing it properly this
season and then make sure to get the surface-feeding bugs during ther summer
I suspect that you will be fairly satisfied w/ it this year and the nice
thing is that you will then be set up for an even better lawn next season.

The main thing to remember is that during the heat of the summer you
shouldn't force it to grow. Your lawn will want to go dormant and you should
let it. Lawns are a spring and fall thing. Most turf species will only green
up in the cool weather. Golf courses keep their grasses green through the
summer by applying lots and lots of water. They also have to bath them in
fungicides to keep them goin'.
