Mixing ferts together

I just got some dry ferts from aquariumfertilizer.com and was wondering if I can mix any of them into one solution. I got Potassium Sulfate K2SO4 , Potassium Nitrate KNO3, Mono Potassium Phosphate P2SO4 and iron chelate.

don't mix the phosphate together. And don't mix the iron in there.
You can mix a little of it together and see what happens. It's kind of cool. They combine to form new molecules. And supposedly it's something the plants can't use.

you can use this calculator to mix the right quantity

might as well just leave it dry and toss it in the tank on a regular basis.

Do not combine the Chelated Iron with any Phosphate fertilizer. They will form a precipitate.

You can mix:
KNO3
KH2PO4
K2SO4
(These are macro fertilizers- plants use more N, P and K than the others)

Did you get any trace or micro nutrients, like CSM+B? This could be combined with the Chelated Iron.

CSM+B has iron in it too.

sorry for the double post, but is there a calculator to show how much iron I should dose?
