PH-5 means you're on the salty side and have salt build up that can burn the roots and cause yellowing. That area needs deeper watering to dissolve the salts and leaching them out. You should also fertilize with a well balanced fertilizer for your grass and maybe add some gypsum to loosen the soil, and adding a iron supplement will also help with greening up and salt control.
Wow, thats perfect! Thanks so much!
Yes I heard gypsum really does the trick as well
