Go to a Hydroponics store. you should find what you need but if you don't see ask.
I am in the Stoney Creek area and get mine from Green Acres Hydro on HWY 8. He usually has to order it for me but I'll have it with in a week, I am sure bigger stores will keep a stock though. The stuff I get is produced by DNF or "Dutch Nutrient Formula" the have a "Six Pack" Nutrient Formula that comes with; Potassium Nitrate, Potassium Sulfate, MonoPotassium Phosphate, Magnessium Sulphate, Calcium Nitrate and a dry Trace mix similar in content to Plantex CSM+B. You don't need to buy the whole six pack if you don't like. Each comes in a 500g container (1.1 lbs) except for the trace which they give less than half the amount (for some reason which I don't understand). the cost is reasonable at about $40 (all in) for the whole pack.
