Why dose ferts separately?

Okay, I have been on the forum for a while and just replied to someone who was asking what fertilizers to dose his tank with. I said that I use Kent "Grow" and Nitro+ to keep my nitrates around 10PPM, but that many people dose nutrients separately. Then I got to thinking, why do many people dose their ferts separately, instead of just using the simple approach that I use? I have not had any problems or deficiencies, other than the one I caused on purpose by seeing what would happen if I stopped fertilizing altogether (long story).
So, who uses the simple approach that I do and who doses separately? For those that dose their ferts separately, why is it that you do that? Is there some particular reason for it that I am missing?

I am an expert on algae, so ask me if you have questions. I know how to grow it, just not how to get rid of it.

Flexibility and full control over nutrient levels. Not all nutrient concentrations fluctuate in sync with each other, so using ferts that target each specific one helps keep them in balance easier.

Sure your method works too and there isn't a correct way. What you're doing it similar to the PMDD method. To each their own.

Ditto as Rolo said. I think this control is more important with high light/CO2 where individual difficiency more readily show up. low light/slow tanks are far more forgiving.

Also, certain nutrients can be dosed dry while others are done so through solutions.

What is in those bottles?

I never felt like I knew what was in the prepared solutions.

I agree with anonapersona. I was using the Dennerle line of ferts but then had a specific deficiency and found I couldn't treat it with their products because they didn't say what was in each one.

Also why would we want to just pour in x ml of a liquid? It's *much* more fun to fiddle around and spend an inordinate amount of time trying to figure out how much to dose of each macro !

Heh, funny. Kent Grow actually says what is in it and how much, that is how I picked it out. As for deficiencies, I don't seem to have any, but the only thing I wonder if I could use a little more of is Potassium since people seem to like to keep it kinda high relative to some of the other nutrients.

I dose individuall because I'm a picky SOB and a control freak!

Now, honestly, one thing I've learned about plant keeping is that there's no 1 correct way to do it. Every tank is unique, and you just have to learn how it works with certain lighting and nutrients and what not. Some have amazing success with PMDD...some try it, and move on to individual ferts.
