In a system holding 30 gallons of
nutrient solution, adding 4 gallons a day you wind up replacing 100% in a week (about 13% daily). At 6 gallons a day you wind up replacing 100% in 5 days (about 20% daily). As the plants get bigger (if they do) they'll continue to use more water daily as well. I don't know if this is an issue yet because I don't know if there's a regular pattern between how much your pH rises, water use (levels), and/or EC/TDS/PPM readings yet in order to compare them.
So does that mean i'll need to add any nutes or just leave it alone and add my PH balanced water and just take notes?
