    How much of that ppm is cal-mag and how much is fert?
    I'm asking because to me it looks like too much P and K.

    Always check EC of water after adding cal-mag, so that way you will know exactly how much other nutes is in your feeding solution.
    For example, in synth hydro I was running maximum of 700ppm (EC 1.4), of which 200ppm was just due to cal-mag. In organic hydro I don't go over 400 ppm (EC 0.8), of which 100ppm is cal-mag. Both were used in RDWC system with 45L main tank and 4x20L buckets.

    I will consider this. As a result I had problems because of too much cal-mag?

    Honestly not sure why your adding calmag to the water. It's a foliar spray and best absorbed as such. Take it out of the feed give them a flush and new nutes without the calmag and just add a little once every 2 weeks to one of the feeds (if they're in flower, if not then use as foliar spray once a week at lights off).

    Tbh I'd say you're also locked out so a flush would be needed either way.
