if your doing e.i dosing with your ro/di make sure you add a bit more mgs04 and potassium. I found with straight ro that i was still lacking these 2 with the gh booster, probably not as big of an issue with lower light though.
That's good to know. What dose of those ferts (dry fert nano measurement, i.e. dash, pinch, drop/ or 1/4 tsp, etc.) would you estimate/ recommend for a 10 gal tank?
And what would be noticeble in my tank from this deficiency overtime?
