The problem is the fertigation strength is tied to fertigation frequency, making definitive answers impossible.
If you fertigate without letting the medium dry, I have noticed I can actually run a slightly higher EC. When incorporating a dry period the substrate's EC can concentrate (though the plants water usage & environmental evaporation). You must account for the possible concentration (generally with a slightly lower EC). (All of this done with recirculating reservoirs.)
This doesnt mean the plant uses a higher EC when watered more frequently, its just the result of a concentrating EC.
