I had a new lawn put in 2 weeks ago. I have watered everyday. The lawn looks good. But there are a lot of area's that are starting to look like this photo. Some spots are worse than others. Some area's have spots and other area's are brown and curling a bit. Most of the lawn looks good. But mixed through out I have this problem. I thought it may be watering during the day, thinking it maybe the sun burning through the water drops. I know not to water during the day or at night. But I had know choice a few days. Does anyone know what's happening. The grass is St. Augustine, my location is Houston, Texas.
