Hey guys, said I would post these pics up but now looking at these red thread pic's in the other thread it looks a bit like my yard also so the more I look the more concerned I get. Up till now I thought it was just stress, the main part of the front yard gets full sun from 11 AM on and as you can see in the pic's, the side is shaded which by the way looks great (well except for a few of my famous herbicide burns) Some of this was present in some photo's from about a month ago, as suggested I raised the blades which made it better. However, I did put a light lime app down on June 15th ahead of 2" rainfall along with a light app of 10-10-10 because I knew these rains were coming and I played the weather. Then, we got hot and humid, 90-95 degrees for the last week solid, one or two isolated t-storms and the ground has stayed wet. Pic's of side to follow. Am I looking at stress from the heat even though I raised the blades, fert burn or red thread?
