Yeah I can’t help other than maybe the plants are drinking more water than nutes. I don’t do any recirc other than a flood and drain table and the EC creeps up with that over the week but it’s only a veg tent so never worried me too much and I don’t check the pH of it (I am super vigilant of pH in flower now though) before I have to refill it. I asked about airstones because I found airstones crank the pH wildly over a 24h window.
