This Calcium Magnesium solution made fertilizing my seedlings and hydroponic plants a easy task. Follow the instructions on the bottle and the results speak for themselves. I can't imagine a more simple way to raise plants for a garden than to use the Hydroponic system and fertilize with Black Magic Calcium Magnesium to get the job done right the first time.

The liquid calcium-magnesium micronutrient was designed to be used in a hydroponics system, but I have been applying it with another liquid micronutrient that contains primarily iron and has no fertilizer value. The first thing that I noticed about the Black Gold was that it mixed well with water and had no settling or problems with blending. I was able to apply it easily to the spring flowers that were just emerging (daffodils, surprise lilies, tulips). I was aware that calcium and magnesium helped to strengthen the cells in the leaves. Not only have my plants been better able to withstand two snowstorms and freezing rain, the little bit of nitrogen in the Black Gold caused a bit of a growth spurt as well. I am anxious to see how this product does when it is used on tomatoes and eggplant, both of which are prone to blossom end rot. Blossom end rot is caused by improper watering and a lack of available calcium, so a liquid application of calcium and magnesium should prevent this common ailment. So far, I'm happy with the product and am using it on both indoor and outdoor plants. It is much easier to mix and spray than some of the commercial-grade powdered products, and it does not clog the sprayer at all.

Black Magic is a high quality source of calcium, nitrogen, Magnesium that is easy to use and very effective on helping plants uptake the fertilizer that is commonly used to feed them. Lots of people have used old farmer tricks like Epson Salts around their roses and acid loving plants to help their growth and blooming. This is my new substitute for epson salts, as I can more accurately measure the amount needed in a gallon watering can and use it around all of my roses, flowers, and vegetables. It will help the plants adsorb the nutrients in organic potting soil as well, grow strong and healthy roots, and I expect to have a great crop of tomatoes and peppers later this summer. Some common sense rules about not letting the concentrate get on your hands should be followed. And 1 quart of Black Magic goes a very long way.

For me this one is a no brainer, because every Black Magic product I've bought or tested has been worthy of five stars. Sadly this one didn't arrive when I ordered it, but from past experience I've used it with great results.I just wanted to see if they'd changed anything in the formula? Last season I had a frustrating problem with tomato blossom end rot. I cut back on watering but the problem persisted. A more knowledgeable friend suggested I try the addition of calcium magnesium with my tomatoes and it corrected the problem. Now I add it regularly. A little goes a long way.

In one set of paper towels I added about 1tsp of Black Magic and water, to another i just used water. Both sets of seeds started sprouting a week later. Initially I could not tell a difference. After planting the seeds germinated in the Black Magic grew faster and had greener foliage. A week later the Black Magic plant were a bit taller. I've started adding some Black Magic to the growing plants hoping to see a difference. But so far so good, a better experiment would have been to compare more plant foods.... maybe next year

I like how it reacted to what I was using it for and it did the job. they give you enough to do the job and then you could use it in small amounts or use the whole bottle. I recommend this product and it will work well. its so worth the money to have and just in case you need it or just have in stock for the future.
