For water column dosing, the chemicals that are contained in the "Green Fertilizer" package will suffice.
You may want to look at a GH booster (which is usually just a mix of calcium, magnesium and potassium sulfates), depending on your water chemistry.
For root tabs, you will want to look into what other people are using.
If you are making the switch to dry chemicals, you will not need the Seachem Comprehensive/Iron.
