so it has been nearly 3 months since i planted my new lawn. the grass was coming in great and looked pretty good outside of a few bare spots and a couple darker and lighter patches. i took the advice from some of you guys and fertilized like i was supposed to. I have been watering 3X/day for nearly 30-40 minutes a day. I used a starter fertlilizer this second time as well and now have a few big dead spots where the grass is browning. They started to appear within a week of applying the starter fertilizer for the second time. Any suggestions????
