Lawn fungus #880535

Within the last two weeks, we've noticed small brown areas that are spreading throughout our lawn. They have what looks like frost in the centers and it's spreading. My husband fertilizer 3 -4 times per season and we have underground sprinkling which we've been using from 3:45 a.m. for 15 minutes per zone to complete 7 zones of irrigation. We have some lovely flowerbeds that like the water. We don't water the yard every night...we let rain take care of it in between. The yard has been treated with Milky Spore for several seasons, so it's not grubs.
The fertilizer is 25-0-8. I'm not sure how much is spread per square foot.
I've included photos below.
