    Hi Jerel. I have observed something relating to citrus and thought I’d see if you have observed the same and know whats going on. This is more in the context of widely spaced trees. The citrus I’ve seen tend to be more chlorotic on the south facing side (the sunny side), whereas the shaded side remains green and even puts out new growth that looks stress free. Do you know what that’s all about? My hunch was that it has something to do with the oxidation of iron in heat stressed leaves due to some other deficiency/issue that would prevent this in a tree with optimized nutrition. Thanks and I appreciate any reflections
