I don't believe in fertilizing a lawn at all. Do you actually want to
cut it more often? s

If you use a mulching mower, no chemicals, and let the clippings lie
where they fall, your lawn doesn't need anything else.

But if you are determined to use a fertilizer, this is not the time of
year to put it on. As you correctly point out, anything that is so
much heavier in nitrogen is only going to encourage the grass to put
its energy into top growth, which is not what you really want it to
ever do.
