Bloom City Professional Grade Ultra Pure Cal-Mag Fertilizer, (32 oz)

I’ve been using the Bloom City Professional Grade Ultra Pure Cal-Mag (32 oz) for my plants, and I’m very impressed with the results. It’s made a noticeable difference in overall plant health—especially with preventing calcium and magnesium deficiencies that can show up as yellowing leaves or weak growth. The formula is clean and easy to mix, and a little goes a long way. I’ve used it with both soil and hydro setups, and it works great across the board. My plants look greener, stronger, and more vibrant since adding this to my routine. Another big plus is that it doesn’t cause buildup or clogging in my system, which I’ve had issues with in the past when using other brands. If you’re growing vegetables, houseplants, or anything that needs that extra nutrient boost, this is definitely worth trying. Reliable quality and consistent results. I'll be buying again!

Did wonders for my plants! Will definitely purchase again.

Works great on all my vegetables

I grew about 10 tomatoes outdoors in 10 or 15 gallon fabric pots this year. I used a calcium rich fertilizer when I started the plants because I knew that nutrients wash away in pots and aren't replenished and calcium loss can cause blossom end rot. I have had it before. The foliage looked good but when they set fruit, almost all except cherry tomatoes showed end rot, some fairly serious. I assume the fertilizer wasn't concentrated enough or washed away to quickly, I bought the cal mag supplement, mixed it 15-20ml to a gallon water and sprayed it on the entire plants in the evening. I live in a hot dry location and was worried about burning the plants so tested it on one plant first. When it didn't burn that one I did the rest. I continued treat the plants, sparying in the evening, about once a week. The end rot did go away, I can't actually confirm the product did it. We had gone through a very hot spell well into the 90s most days and with 20% humidity when I first noticed the problem. The weather let up a bit at the same time I stopped seeing the end rot. I might have changed the watering a bit too. It's possible it would have gone away on it's own. But I continue to spay once a week, it hasn't come back, and we have had some hot days since. So it didn't hurt the plants and maybe it helped.

Tomatoes love this fertilizer definitely a good buy!

I bought this concentrated Cal Mag fertilizer because my plants were starting to show signs of nutrient deficiency (yellowing leaves and drooping edges), and the results have been amazing in just a few days. What I liked most: Exceptional performance: Being a concentrated formula, it lasts a very long time. A very small amount diluted in irrigation water is more than enough. Visible and fast results: The plants regained a vibrant green color and firmer, healthier leaves in no time. Complete formula: The extra supply of calcium, magnesium, and essential micronutrients has strengthened both the roots and overall growth. Easy to apply: It dissolves perfectly in water without leaving any residue or clogging sprayers. Conclusion: If you want to prevent nutrient deficiencies in your plants or give them that extra boost during the growth and flowering phases, this Cal Mag is an excellent investment. 100% recommended for any gardening enthusiast.

This stuff really works! I had Blossom End Rot in one of my tomato pots, so I decided to give this a try. Within a week, all of the affected tomato's were improving and within two weeks the Blossom End Rot was gone!

Tomatoes were really small and had bottom rot this stopped it and made them bigger
