I fertilized with 16-4-8 on Memorial Day and will admit I may have overdone it slightly but had good rain for a week after so I figured I was still good to go. I did a mixture spread with fert, insect, and some spare brown spot preventer I had laying around. I noticed I am starting to get these brown areas popping up randomly. Overall the yard is filling in nicely for year 1 but I can't tell what is going on here. Is this fert burn? Would that be popping up this late? Or am I starting to get brown patch? I have an event at my house at the end of the month so I am trying to be extra precautious.
