Q.Pea Plants Are Yellowing

Anonymous added on April 11, 2011 | Answered

Our pea plants are up about 3 inches. We live in south central New Mexico. The soil is sandy but we’ve amended it with peat and compost, plus we are using an organic fertilizer. About a week ago, the plants began turning yellow. Is this a lack of iron? If not, what is it and what can we do about it? We water in the morning and the late afternoon. The water here has a high calcium content.

It is iron chlorosis, but typically, the plants get it because they simply can't get to the iron in the soil. Given what you described, I would say either you have too much phosphorus or the pH is too high. This article will help with fixing that: https://www.gardeningknowhow.com/plant-problems/environmental/leaf-chlorosis-and-iron.htm
