You need to add
calmag bro. Better products than GH
CaliMagic are MagiCal and
CalMag +...... 1/2 tsp to 1 tsp should do, my tap is 110 ppm at 27 grams Ca and 7 grams Mg..... plants like OGs, etc (aka
Calmag whores) will definitely need more than what's provided by your tap.
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.
