anyone know why my ph keeps raising? i made a 4 bucket recirculating system with just sprouted seedlings so it is just plain water ph 5.8 then the next morning its already up to 6.6. i ph it back down to 5.8 and it goes right back up. are they just telling me they're ready for nutes this early? thanks
or could it be hydroton dust from the bottom of the bag that fell through when i was filling the pot? i didnt worry about it when it happened because i thought the hydroton was stabilized and would not affect it
