    Hey buddy what's the ph and ec of your feed? Looks abit like a ph problem or possibly hard water locking out magnesium and calcium. If your using ro water you might need add some calmag. I'm only going from an issue I had very similar and it all cleared up and even a few leaves healed themselves after a 60l flush with bottled mineral water instead of tap water because I had very very hard water. Yours looks more of a ph issue though or calmag issue if your using reverse osmosis

    Thx for the reply m8
    It could be exactly that.I also have very hard water and I'm not using ro so I'll try giving them bottled water for few days and see how will that work.I don't think the ph is an issue since all the ferts are organic.
