I would highly recommend using this on your pot plants and you will love it come harvest time. ### ⭐⭐⭐⭐⭐ It's calmag *by on Reviewed in the United States May 15, 2026* What can I say ? It's calmag. Great supplement when running in coco coir especially if running soft water or reverse osmosis (RO) water. I really like the Canna Coco nutrients and I've have been having great results my first run using them and it's one of the most simple nutrient lines to use. Instead of 7 different bottles I now run 4. 2-4ml of calmag agent and equal parts of A+B. Can't get easier than that. I also got the PK 13/14 but haven't used it yet. ### ⭐⭐⭐⭐⭐ Worth it! *by on Reviewed in the United States March 2, 2026* Item arrived fast and packaged really well.I was surprised how good this Cal Mag is and I will be buying more of it.I would recommend this seller and product. ## Frequently Bought Together - CANNA Cal Mag 1 X LTR !Big Yield Taste/Increased Aromas!Wow!
