The Penn State turf folks have been on-site and did soil testing. Nothing too out of kilter.
FYI: The consensus from Penn State was my pH was too high. With the addtion of the injector and me testing weekly... Didn't seem to correct the problem.
Do you have the results? Trying to fight your soils natural pH is a non-stop battle. You would be better off finding/using a turf that is suited for your soils rather than trying to make your soil suitable for a particular turf.
There are many different varieties of KBG. If the Penn State ID didn't differentiate between different varieties, then that is your most likely explanation for this color difference even if this has been going on for many years. Easiest way to fix it IMO is to vertimow and overseed with the same variety until you get better uniformity.
