    Default RDWC Rising PH issue please help ASAP

    Started my four pot system - Under advise I mixed the nutes in the brain and not the res as the clones are only small and don't require a lot of water.

    Using the Shogun range

    A+B.
    Cal Mag.
    Root juice.

    After adding the above

    Source water EC 0.6 Add nutes to make this 0.8.
    Set PH 5.8

    24hrs later Water level and EC remain static however the PH as swung all the way up to 8.0. How can this be? and what are the possible solutions for this?

    (I have double checked) both PH and EC pens are calibrated correctly. (blue lab pens )

    Pics?

    Also ph rising whilst ec static is not a problem, just keep knocking the ph down. Are you finding nute mix has evaporated away a bit making a more nute rich feed?

    Can i ask why the cal mag with a bg ec of 0.6? is the water hard or soft? do you know the tap water ph before adding anything>?
