Using commercially prepared ferts

[KnaveTO]

Alright... I have seen tons of documentation and information on using dry ferts or PMDD and the like. I cannot seem to find info on using the commercially produced ferts.

I live in a small apartment in the middle of a large city and getting and storing all of that is more than I want to deal with or can deal with. That being said I am currently using Seachems Flourish line of ferts and was wondering if there is anything out there on dosing such premade commercial ferts outside of the recomended dosage on the bottle as they can be and are wildly inaccurate as they do not take all parameters into consideration.

Please... I don't want to get any lectures on how I am wasting my money by purchasing such, nor do I really want to hear how I can buy small quantities of the dry ferts and mix them up... I don't want to have to buy a bag of stuff and have it sitting around here a year later.

Thank-you

I use tetra's fertilizers, and I use them at under 1/2 concentration. My plants seem happy...
I think the dosages on the bottle are for massive growth so that you say "wow, what great fertilizer". If kept at that level though, I'd be pruning stuff too often.
