Fe - iron
K2SO4 - potassium sulphate
KNO3 - potassium nitrate
MgSO4.7H20 - Epsom salts
9M HCl - 9 Molar (i.e. very concentrated) hydrochloric acid
K2SO4, KNO3, and trace element mix are available at hydroponics
shops. Epsom salts can be phound at any pharmacy. Hydrochloric acid
can be obtained from hardware/home renovation stores. If you don't
know how to handle concentrated acids, skip the HCl and keep the drops
in the refrigerator.
