There are lots of ways. Some easy examples are putting things like a simple eggshell or oyster shell for calcium, banana peels for potassium, etc. Tap water/well water often has a lot of minerals in it already. Compost or worm casting tea can work quite well too. We have a member on here that has a hybrid system with the worm poop built into his aquaponics!

It depends what form it's already in. If you read me the ingredients from the label I can give it a shot. That's not the most cost effective way to do it though. Water soluble fertilizers are much cheaper.
