    the waters ph is 6.5, do you have any idea what the soils ph is?
    and the ph level after adding canna vega with the water??

    the first picture looks like Black Spot Fungus, but picture 2 looks more like a lockout
    It could be a simple pH issue or even a nutrient deficiency/lockout.

    really need more info

    Once ive added the Canna the PH drops right down so I PH it back up to 6.5.
    I haven’t got a clue how to PH the soil?

    Maybe you should check ph of potting soil first.
