Hi Dan, yes I did see the UC Davis fmv report this is why I was confused because the leaves certainly look like they have fmv in fact all 3 of the kadota seeldings have these markings on the leaves. My other seedlings however do not show any signs of fmv or have not yet.
Next season I will play with put them in some composted lamb manure and see what happen's. I guess like you said there could be a possibility that it could be nutrient imbalance if im not mistaken these 3 seedlings are in Miracle grow potting soil. Everything else I have is in Pro-mix BX mixed with Composted Lamb Manure.
