    Hi Darrin. I have seen what you are talking about. Growers here all just call it sunburnt leaves. It doesn’t look like iron chlorosis but just a general yellowing. It is worse if the grower sprays oil for mites or scale. But I wouldn’t know exactly what is going on in the leaf chemically or physiologically to explain it.
