Water Change Day?

[TarkMalbot]

I'm dosing Macro and Micro on alternative days 6 days a week with one day off. Which day would you do your water change? I have just done a 50% water change but it is also my day off dosing. I take it there is enough ferts in the 50% of old water to keep the plants happy until the dosing starts again tomorrow?

I wouldn't worry about it. If you're doing EI then the plants won't go hungry, even if you miss a few days (unless you're running incredible levels of lighting, CO2, and have massive plant biomass).
