Ok so you're thinking macro nutrients!
From memory, 1/2 tsp KNO3, 1/8 tsp KH2PO4, 1/8 tsp K2SO4 (3x per week, weekly water change)
For the CO2, I measure it with the dropchecker, I have it green, but maybe as the plants grew I should have added more because now it's a darker green. Should I aim for almost yellow?
