Nah man. Ur probably not gonna need any calmag w canna and 150ppm tap water.Hi farmers I have question about my tap water. I read 150 ppm around 0.3 e.c. Calcium is 44mg/l, Magnesium is 10 mg/l. What this numbers say? do I need to supplement extra cal and mag with my tap. I grow in Coco with canna coco nutes a&b. Thanks for help.
With my RO water in coir I strive for 70 ppm cal, 25 ppm mag and 10 ppm of iron for my base water.
My tap is 110 ppm (0.2 EC) and 7.6 pH and I use Canna Coco A&B at 10 tsp of each to a gallon of the tap. Puts me about 700 ppm (1.4 EC) and whenever i add a Calmag product with most of my strains (doesnt matter the brand) they start acting wierd. Purple stems and slow growth. I believe its too much cal and or mag. Did it recently just for the hell of it on some extra plants i had. They were fine with the Canna base....i just wanted to see. At about 2.5 - 3 ml per gallon of tap....the calmag with Canna base plants started acting funky. So i keep Calmag on hand...but only use it sparingly if at all. Ususally its when they first go from rooted clone plug to first pot of coco (Canna Brick) that they MIGHT show a problem. But once they are chugging along in final pot....i usually not dare add calmag. Not even a little. Now with Ionic Grow and Bloom as a base with coco coir....its a different story. The 110 ppm tap and Ionic just isnt enough calcium and or magnesium for alot more of my strains.
What for nutes line do you use?
