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.
