They serve these purposes: (B) Boron
Necessary for the formation of cell walls when combined with calcium. (Ca) Calcium

Nitrogen metabolism and fixation.
Protein synthesis, water uptake , fruiting and seeding, natural fungicide. (Zn) Zinc
Chlorophyll formation, respiration and nitrogen metabolism.
Most nutrients are listed with the amounts of N-P-K represented in percentages. For instance, a 10-10-10 solution would contain 10% Nitrogen 10% phosphorus and 10% potassium by weight. If you do the math, you will find this concentration adds up to only 30% - this is because the remaining percentage usually consists of a filler of chelating materials used to assist the nutritional process. Use only nutrients specifically designed for hydroponics, as conventional formulas prepared for plants grown in soil do not contain the proper balances. I personally favor the two and three part nutrient formulas as they always outperform the general purpose nutrients. The two and three part formulas allow you to custom blend for each crop and stage of growth.
