Heat stress or fungus? Located near philly and lawn is 100% tttf Went on vacation for a week and came back to these spots forming all over my lawn. I basically live in the pine Barren's which has very sandy soil so we water more frequently/shorter durations . Im currently watering 4-5x a week at 10 mins a zone Soil isn't really dry which is making me think its a fungus? Originally by u/crypt0bitcoin on Reddit: https://tinyurl.com/ymbopczw
