I seem to be having some problems with powdery mildew and possibly something else as well as some of the blades are starting to yellow.
I set this up to track my progress on converting my MN front lawn from a mix of RyeGrass, Fescue and KBG to 100% KBG mix of 33/33/33 of each of the following cultivars - Midnight II, Kingfisher, Bewitched. Also 2015 new seed 33/33/33 Award, Bewitched, Prosperity (Seed Super, Seed Super, Pawnee Buttes)
