sorry to double-post ... next time, do what I do, just for shits and giggles, ... I always throw a rusty nail into the soil, when planting, then you'll not be wondering if you have an iron deficiency ... beyond that, I'm not real sharp on nutrient deficiencies ... I almost never have ailing plants, and I never did much more than the rusty nail, and a weak dose of Miracle-Gro once a week, applied foliar-method, both sides of leaves ... hope that helps .. :smokin:
