Somewhere around here I might still have slides from a hydroponic nutrient deficiency experiment I did at Cal Poly about 35 years ago. My partner (co-experimenter) and I mixed our nutrient solutions using distilled water, etc. and had some useful results. I'm sure information has advanced over the years since then and my memory of things the particulars is pretty limited. The only thing I remember is that iron and nitrogen deficiencies appeared similar.

Edit: Oh, and I remember my roommates appreciated fresh greenhouse tomatoes in the winter!
