    I've changed my mind..... potassium deficency, which could be related to the lower RH being mentioned...

    If it wasn't for the necrosis in the last set of pics, I'd still be questioning zinc but it looks like potassium has sneaked in under the radar!

    I dont need to ph generally.

    Water starts at 7.3ph 0.4ec.

    I add my nutes including the cal/mag (which has a negligible effect on the ph for me.)

    This usually gives me a ph of 5.8 ec 1.3.

    I only tend to use ph down in the early days when adding little nutes so not reducing the ph enough.

    Dont want to confuse the op though as Im talking hydro.

    But some info on the cal/mag I use

    Prevents and cures magnesium deficiency which causes yellow leaves and boosts the effectivness of your PK. Also regulates nutrient transport and strengthens cells and supports photosynthesis and enzyme processes. As well as Calcium and Magnesium for healthy growth, Magne Cal+ also Includes a full complement of trace elements

    Total Nitrogen (N) 8.0%

    Nitric Nitrogen 7.0%

    Ammoniacal Nitrogen 1.0%

    Water-soluble calcium oxide (CaO) 7.1%

    Water-soluble magnesium oxide (MgO) 3.5%

    Iron (Fe) chelated by EDTA 0.04%

    Manganese (Mn) chelated by EDTA 0.01%

    Zinc (Zn) chelated by EDTA 0.006%

    N 2.6%
    P 0.1%
    K 0.3%

    The brand I use does not say whether to water in or drench it just says apply lol.

    I like it for the traces it includes also.I find I hit problems without it and always use it,especially through flowering as it helps with p/k uptake.

    There are organic versions for soil.

    Op Just give a good feed of whatever you have with runoff adding a little cal/mag if you have it.

    Wait till you dry out a tad before repeating.It will take a few days to see what effect (if any) this has.
