Hello Agraco,
First where are you located?
Do you have a link to the Superman and Gigaboost? I've got a hunch they are just additives. The Cal mag is defiantly just an additive, and the NPK numbers are extremely low for a balanced fertilizer on the other two as well. For a stand alone balanced fertilizer I would expect to see a NPK ratio of something like 6-12-28. not 1-2-1 or 0-3-3. Trying to get a balanced
nutrient solution out of additives is very hard to do, not to mention very expensive.
