Need trace elements

is there a nutrient solution that only gives the trace elements, instead of the main n-p-k and secondary? Is there one from major commercial brands like miracle-gro or shultz? This way i can feed my plants a vast range of hydroponic solutons. Something new for every growth stage...

Liquid Karma is a great product for adding to existing fertilized hydro set ups.
It contains a wide spectrum of trace elements.
It is available in most hydro stores and costs about $60 a gallon.
