Possible fertilizer? (chelated Fe w/ minerals)

Its label reads as follows:

Mg    0.50% (chelated)          Mn  0.25% (chelated)
Sulfur     3.90% (combined)     Zn  0.50% (chelated)
Boron     0.02%                 Cu  0.25% (chelated)
Fe        6.00% (chelated)

The ratio of Fe to Mn is 4:1 in the hydroponic mix that
I use, so maybe more Mn would be preferable. Also there
is no molybdenum.
