thanks for all the suggestions but you know i went back out on the lawn and took a close look a the real issue is what looks like drought is really brown spot and dollar spot, the Rachio is doing such a nice job of watering the lawn that what is really happening is that healthy grass + water + fert + heat = fungus. I went out and got some Bayer Lawn Fungus Control and just put it down on the entire yard and hopefully nip this in the bud.
