difficulty in getting nutrient for hydroponic

[ten]

dear Ron,
i am having difficulty in getting nutrient for hydroponic system from where i am. furthermore, i cant find any chemist who will do the formulation for me nor guranty that the nutrient mix is correct.
right now, i am using 30-10-10 for my veggie. the content are as follow :
N ... 30% P2O3 ... 10% K2O ... 10% Magnesium ... 0.120% iron ... 0.040% manganese ... 0.020% boron ... 0.015% copper ... 0.007% zinc ... 0.005% molybdenum ... 0.002% calcium ... 0.090% vitamin B1 ... 0.075%
will this water soluble fertilizer work in hydroponic system ?
thanks,
