- Environmental stress

This is often caused by sunburn- direct sunlight striking leaves. This occurs more frequently in early spring on plants with poorly established root systems. Other causes are fertilizer burn from foliar applied fertilizers, cold water sprayed on plants or pesticide spray injury. Healthy plants will outgrow the injury.
