    Feeding calmag buggers up your ph
    Only ever spray it 1ml pl drench them all over
    And under the leaves.

    Once at 2 weeks old then 2 weeks into flower.
    As a precaution.led bring out mag defs for some reason
    And 'I think' that's wot that is.at a guess without
    Normal light pics.stop feeding and brush the affected
    Leaves with the solution see if it stops it.
    Might aswell brush all leaves if you can too.

    Don't go by feed charts also,go by the color of the leaves
    That tells you the health of the plant.not too light an not too dark.
    I tend to go with a well fed dark color but not really dark just out
    Of light green if you get me.jus feed to get that color.if they go lighter
    Give an extra ml feed if they go darker jus give plain water for a water
    Then back on the feed.

    Hi Erb thanks for dropping in to help. Would the advice about when to feed cal/mag still stand even for people like me with soft water? Cal/mag saved my last grow that's why I just want to make sure. Also when you say brush the affected leaves with solution are you talking about just water and cal/mag? I will snip a couple of leaves off when I'm home from work and get a better picture with some decent light. Thanks again for helping me out guys.

    Oh and I have been feeding calmag at 0.5ml/pl for pretty much most of my grow. I can try drenching them with a sprayer from now on but the way I have the plants tied there is no way to get round the back of em to spray. They have taken up the full size of my tent! Still learning.

    It's just good practice as a preventive measure that's all : )
    Don't spray them now as they are flowering now.
    That's why I'd brush with clean paintbrush.
    That's if it is cal or mag.wouldnt go chopping off
    Good leaves mate jus take a few pics when lights off : )

    ERB is on the ball as always, looks like a cal/mag issue.

    At certain times like heavy flowering the plants need an extra boost of cal/mag especially if your in a softwater area.

    I have problems with cal/mag even in a hard water area, so I do add it to my feed, but I also add amino acids that help to chelate (claw), the calcium molecules and stop then turning into lime scale in the reservoir,

    I wouldn't worry too much at this stage thou, as its a very mid case at the minute, i was just spot treat as ERB said

    I had same thing a few years back and it was down to using pm oldtimer grow along with their root stim which needed ph'ing. Twat in shop said you got to so i do and it fucked my plants. Bud lightyear gave me sound advice to buy a bit of trichoderma to repopulate the microherd which i did and stopped using root stim and ph'ing and it saved my xmas smoke. i owe that man big time for helping me along over the years.

    Hey.

    That's interesting for sure. I didn't have any issues at all when I was using the Root stim I haven't used it for around a month and also haven't paid attention to PH at all this grow. Gonna have to look into Trichoderma I haven't heard of it before now.
