    Default Can anyone help me identify the problem?

    Plants are about 7 weeks old. Last week they started to turn yellow and now gaining brown spots. They are grown in coco and perlite mix. Can’t decide if the problem is to do with nitrogen, calcium or magnesium. Or maybe over feeding??

    We use Cana A & B.
    Rhizotonic
    Cannazyme
    Carbo load
    And a silicone supplement.

    Thank you for reading.

    Actually, they just look a bit hungry to me. If you are starting into flower it would be okay to feed some cal/mag that may have some N in it, or you could probably just up your feed a little bit. once you're into heavy flower you'll want to plant the yellow out and start giving up its chlorophyll and most nutrient programs are tailored that way.

    Yeah the food has been measured. We have them revive yesterday as the cal mag hasn’t turned up. They are still going yellow and lower leaves dying. Will wait to see if there’s any change. Thanks for the help.
