This is a must have for those who grow medical MJ or any other crop that is cal-mag hungry. Before I started using this product I would have yellow dieing leaves within a few weeks of flowering. Now my plants are nice & green at harvest time and yields have increased. I use with every watering starting half way through veg. The organic soil I use provides enough cal-mag for the first month of the veg cycle. In veg I give the plants 1/2 tsp per gallon. After the first 2-weeks of flower I raise it up to 1 tsp per gallon. Depending on your soil and other amendments these #'s will change. Always start off low to prevent over feeding.I also have friends that grow in a hydro system. The all use this product with great results.I highly recommend this product.

If you are using Coco Coir then you absolutely have to supplement with Cal-Mag Plus. This product is an essential supplement when buffering Coir and growing hydroponically with Reverse Osmosis water. I use it every time I water/feed my plants. It is important that you add nutrients to water in the correct order to prevent nutrient lock out so always add Cal-Mag Plus before any other water soluble nutrients. It can also be used as a foliar spray just adjust the mix ratio according to the directions. This can and should be used in addition to any Micro nutrients you use in your regimen. Cal-Mag Plus works and is my personal preference when supplementing Calcium and Magnesium and Iron.

When my Tomato and Pepper plants were showing fast signs of Blossom End Rot on the 1st round to mature this past Spring you could say I was a bit discouraged because I'm a firm believer in proper soil prep for good growth. Apparently my soil had issues and too late to remedy the deficiency in the soil, however, this liquid application remedied the deficiency quickly with continual application for my plants and I got my expected abundance of veggies...

Ok. We use it on a few plants, but all hydroponics, cor the vegetative stage it worked ok, but I couldn't seem to completely fight of deficiency with this product, however when switching to the flowering stage, the plants suffered through the whole way, yields were greatly (up to 50%)reduced with our clones as compared to past using calimagic. I wont make this mistake again. A 20% savings is not worth 1000s of dollars in lost yeilds.

When using distiller water there are no macro nutrients like magnesium and calcium and iron. My plants would turn yellow because of this. A day after using cal-mag they immediately started to improve. Just what I expected!

This is an excellent fertilizer for calcium and magnesium deficiencies that may crop up in the garden or in house plants.
