    Default Doh!

    I bought a bottle of Vitalink PH Down.... opened it today, added the approximate amount to my water... reading? 7.2

    Recalibrated my PH pen, it had drifted 0.2, so I was happy

    PH tested the water again.... 7.0 FFS!

    Looked at the bottle... then compared the bottle to my old one. This is 25% & the old one 81% - Never realised they did two different strengths and the difference on the bottle markings don't make it obvious

    .... and that explains why I thought it was cheap

    First time my ex did the big shop online she ordered a pack of ham for her and the kids, she thought the same "ooh that's cheap" When it turned up it was enough for a sandwich just looked massive in the picture

    I was surprised at the drift, normally I get a whole grow without having to re-calibrate
