If the water goes down and the PPM's are going up your probably over feeding the reservoir and they dont grow, lol. My theory on PH drift is the feed mix sets the PH and different nutrients and supplements raise and lower the PH so as the plant consumes more of one than the other the PH changes. That could be total BS but my auto feed and ebb & flow reservoirs stay set if anything they climb a little. The RDWC is a different story, I will use a gallon of PH UP in a grow but its on a PH dosier
My 2nd try at hydroponics is it normal for ph to drop and ppm go up plants only taking water it seems do I need to add more air to the resivor
yeah its normal plants will only use what nutes it needs i usually just add water and ph until its time to change the res.

I dont think air has anything to do with it
