Dosing ratios

I am not using any fixed ratio of ferts like PMDD or anything else.I am just using testers and mesuare independantly NO3 PO4 and iron.I use KH2PO4 for PO4 around 1ppm ,KNO3 around 15-20ppm and I use a commercial fertilizer(sera's)until I reach 1ppm of iron with the test kit.I hope this covers my needs of micronutrients.The other thing I know is that some of you add sulphates whitch i don't know how important this is.I also don't know if you do this to raise you pottasium level(KSO4) or sulfate level.
I would like to see your comments

K2SO4 is used to raise potassium. The sulfate is added too but that isn't an important nutrient to dose. You could think of it as a by product. I'm not aware of any importance in sulphate dosing...
