Hi, I hope someone can help me. I'm growing mephisto under 50w cob lights. In Coco/perlite mix and feeding all canna nutrients.
I think my problem is a magnesium deficiency which I keep getting just as they move into flower. I use calmag each feed at 1ml per liter minimum up to 1.5ml. If anyone can be of assistance it would be much appreciated. Here's some pics.
