Red Tips and Yellow Blades in Lawn
Discoloration of grass blades is fairly common and there are two main color issues to look for. In this video Doc shows you some red tips and how he deals with them.

Red Tips on Grass
First, red tips on the grass are caused by two main factors. Cold snaps causing stress damage is the main cause, but also low phosphorus levels can do the same. I strongly suggest a soil test if no cold weather has been around for weeks. A soil test will reveal the needed fix.
Yellow Blades of Grass
Yellow blades are caused by chlorosis. Iron chlorosis results when green chlorophyll in leaf tissue fails to develop. Although iron is not part of the chlorophyll molecule, it is one of the nutrients essential for chlorophyll synthesis. Iron chlorosis first develops in new growth and appears as yellowish-green leaves, usually as an interveinal yellowing, giving the leaf a striped appearance. As the condition worsens leaves appear yellow to almost white. In severe cases of iron chlorosis, loss of turf grass and other plants occur in irregular patterns.

Iron chlorosis presents a significant problem to crop production in the southwestern United States. It is most prevalent in high pH, calcareous soils. In such soils the growth and appearance of many plants, including turfgrasses, are impaired by iron deficiencies.

Iron chlorosis is attributed to reduced availability of iron in calcareous soils and may also be associated with high levels of bicarbonate and phosphate in plant tissue.
