i agree the nutrients are just as important but i noticed when i started dosing KH2PO4 and KNO3 along with seachem flourish and flourish iron the plants looked better more vibrant colors with the co2 i just ment the growth rate its phenominal one of my plants is a good 3 " taller than it was before co2 10 days ago.
