Optional
2-4ml-Fe/Iron 3x a week

If your plants are showing signs of potassium deficiency, you need to start dosing K2SO4.

2. and what is a GH booster called by name?
GH Booster... :-) I think Tom Barr sells it. Or you can use Seachem Equilibrium.

Yes. Plantex CSM+B is one June of trace mix.

greenleafaquariums.com also sells GH booster.

some suggest that if you have plenty of livestock you don't need to dose Nitrate or Phosphate, but you do need to dose Potassium and trace

GH booster is comprised of CaSO4, K2SO4, and MgSO4 in a 3:3:1 ratio, respectively.

In a highly lit, heavily planted aquarium, there will not be enough nitrates and phosphates to meet the demands of plants.
