    Default Rapid ph h drop rdwc????????

    Hi guys, i am totally baffled as to what is going on right now with the ph levels.
    A rdwc system with 4x 55 litre pots. Ph levels have been fine right from the start up until now, we are just about 3 weeks away from harvest atm. Everything looks good on top. After a full system water/nutrient change, just overnight ph dropping from 5.8 to 4.7.
    Usually when my water/nutrients are added into the system with the airstones adding air it usually rises not drops? Anyone any ideas? I really dont know what to do. Cheers

    Asking the same question in different threads gets confusing for all...

    Keep it one question per thread please...
