Cal/Mag Pro Series - Hydroponic Plant Nutrients - Supplement for Enhanced Plant Growth - Naturally Derived Premium Powdered Nutrient with Calcium and Magnesium for Soil, Hydroponic, & Coco Coir 60oz

This product works exceptionally well, My plants were turning yellow due to nutrient lockout and using this Cal mag product had an almost immediate effect. Within 10 days or so they were green again and started to put on more mass. This is good stuff, it goes a long ways so don't waste your money on liquid because then you're just paying for water, just buy this.

Works like a dream

Enough said, if my pictures don't convince you all to try this stellar nutrient pack then there are bigger problems with your grow. I have never encountered a nutrients pack that has been such a beautiful blessing. Thank you so much.

Tried it in ther sampler pack and I liked it I think even tho its a pain administrating itHad to have it after it was goneI like the high nitrogen count also

Great

Good price

It works great but kind of the same complaint as other reviews. It’s a little chunky and isn’t completely water soluble, still had a few solid pieces at the bottom of my watering jug after mixing. Overall still a good product just need to get their milling better so it’s a finer powder.

Love it! Had no issue dissolving in my water .. my other notes mix with it well, and most of all performance. Enhanced my grow. My ladies are so happy with it! Recommend it!!!!! Great amount too! Stoked!!! Buy it!!!!!
