    Default Could someone assist on this please

    Okay,
    Temps 25-27
    Rh 50-60
    600 viperspectra 100% veg and 20% bloom on
    Hanging around 24 inches away
    Noticed various deficiencies so flushed pots checked run of ec in was 0.9 ec out ranged from 0.4-0.6
    Ph I thought was 5.7 (ph meter was out so it was 5.3)
    Meaning the ph on run off was 4.9
    Everything I'm doing seems to be fine apart from the ph being F'ed up so is this PH off balance? Light to close? Or something else?
    Northern lights auto showing major calcium deficiency even after 3 separate sprays of magnecal at 2ml as well as 0.5 in base feed
    The zkittles the biggest one just seems hungry to me and the others I have no idea what's going on

    My thought too, probably caused a lock out with the low Ph. Flush as you have and start again with fresh Ph'd nutes and they will bounce back soon enough

    NO SELL, NO SMELL, NO TELL!!!

    See I thought underfed too but figured with them being autos and still only so you 0.8 ec would be well high enough hence why I checked the PH, I could get a lights of photo real quick but not of individual plants as it takes ages for me upload

    After a closer inspection is it possible for a phosphorus deficiency to look like cal deficiency? My zkittles has a tiny tinge of purple on one of the lower leaf tips, all of them have a very deep purple stem too, so I'm thinking this is what it is due to the low PH, hence why the misting with magnecal didn't help the NL? I assume my feed is okay
    0.5ml canna A and B
    2 ml canna rhizo
    0.5 ml plant magic magnecal
    Every fifth watering 0.5ml vitalink silicon

    Stop telling us how much you are adding & start talking in EC...

    What is the EC of your tap water?
    What is the EC of your feed?
