Increasing Potassium for Hydrocotyle pinnatifida???

I just cant grow H. Pinnatifida! I believe my light, CO2, ferts are fine. Other plants are doing fine. I already dose POTASSIUM NITRATE [KNO3], POTASSIUM SULFATE [K2SO4], and MONO POTASSIUM PHOSPHATE [KH2PO4]... Would increasing one of these be worth trying?

If you want to increase potassium levels only, then potassium sulfate is the way to go.
Thanks Anthony
