Heat is not the problem. 60s for highs. I agitate between apps and it's a pressured cross tank agitation.
The N rate is high, but not more than I have always applied. This season is the only variable, and not all lawns are browning. Only a select few, and mostly in areas that are shaded and probably stay damp but I always apply less in shaded areas. That is why I wonder about fungus.
