    Looks like the start of nute burn. I don't give my organic grows cal-mag! I only use it with soil-less substrates. Do you have a EC meter? If you do, then get an reading from the run-off. If you don't have one, then you need to get one.

    Looking at the NPK values (9.6.17) of your nutrients I would guess at a Potassium issue

    My issue is the added calmag and mega crop in an amended soil!!!
    What amendments are you using?
    You say the ph is 6.5 is this how it is out the tap or are you using ph adjusters at all?

    Ok to clarify further, I only use 50% recommended cal mag and 40% recommended megacrop. This soil was amended in the summer and there was a male that grew it this pot (by mistake) before I had to cut it out and plant a female. I cleared roots from soil and reused it. I cant use tap water it is garbage around these parts, I buy drinking water that I mix stuff into. Are you call sayin I should flush it out ? Thank you for your input

    No one has said flush yet, they're getting to grips with the soil & feed first....

    If you are UK then your tap water will be fine.

    How have you amended your soil?

    The reason I said about your nutes is that it is well out of whack for cannabis The potassium is too high & (shamelessly copied/pasted from the net)

    Symptoms of potassium excess:

    • Blocks the absorption of other elements such as calcium, magnesium, zinc and iron.

    Not in the Uk but trust me tap water here kills pets and plants. I didnt personally amend the soil a friend of mine did so I?m not sure what was used. I just figured most of it was used by the precocious plant and the first 6 weeks of the current plant

    Your reusing soil mate, to start your using distilled water which will have nothing in it so straight away your missing humates not to mention what else unless you reamended properly.

    One things istrye cannabis like a lot of potassium! But it’s the lack of other essential minerals etc your missing I feel
