Is it better to use All-In-One Fertilizers (Flourish, Hagen Plant Gro, Tetra Flora Pride, Leaf Zone) or is it better to buy each nutrient seperate (Flourish Line, Pfertz Products, Amano Line)?

In my experience, Flourish was a great product on its lonesome, but it works even better if you're dosing macro nutrients along side...

My I also recommend that if you are dosing, with or without CO2, to go ahead and add Flourish Excel too, it helps a great deal with algae control.

Rex has a pretty good plan for fertilizing. Here is a link. Of course it matters how much light and co2 you are using.

The reason for dosing KNO3 and KH2PO4 as separate fertilizers is not that it is "best", but that it is by far the cheapest way to do it, and the most flexible way. When you buy liquid fertilizers you are buying mostly water. I already have plenty of that.
