Those are hugely high N numbers on both. I feel confident now saying you have a bit of N toxicity. If it were me, I would discontinue the use of calmag altogether. Let it go without for at least three straight feedings (that should be more than a week) and see if they start to improve. Best suggestion I can give you. !5%, wow. @Emilya, I'm tagging you because I very much don't want to give this man poor advice. Would you be able to chime in here please when you have the chance?My bottle reads a little different. No Ca at all, and S is higher. It does have Ammonium Nitrate on the label, and most times it's Calcium Ammonium Nitrate that is used. There's probably some Ca, just not accounted for. Fox Farms does the same thing on their labels.
