Specifically the CAL -MAG products have worked amazing on my tomatoes. I have picked over 200LBS of Red and Pink Brandy wine tomatoes and not one with blossom end rot. I have had no deficiencies. Along with help from mainly other TPS products plants are 10 feet tall and tomatoes average over 1 pound. My largest Pink one was over 1 lbs 10oz, Excellent product for all plants. ### ⭐⭐⭐⭐⭐ Great supplement *by L***N on February 3, 2026* I use this in my container garden for my tomatoes and peppers. Highly recommended, particularly to help prevent bottom end rot issues. ### ⭐⭐⭐⭐⭐ A calcium/magnesium supplement is often necessary to prevent blossom end rot in tomatoes and others *by J***. on September 2, 2024* I grow most of our veggies and herbs indoors, and this is one supplement that I often use for my tomatoes, peppers, squash, both yellow and zucchini, and for lettuce. The plants that seem to require additional calcium and magnesium are the fruiting plants, such as tomatoes, peppers, and squash. I also grow a couple varieties of Romaine lettuce that this supplement helps to prevent a rot that sometimes happens at the crown of the plants. In the past, I have been using a similar supplement that has worked well. It requires 4 cc's per gallon as does this supplement, but this one contains more nutrients and a higher percentage of calcium and magnesium. In addition, this supplement includes micronutrients that my previous brand did not include. Since I bought the gallon bottle of this supplement, using it at 4 cc's per gallon, it will last me for a few months. I am happy with the results I have seen using this fertilizer, and it has helped to reduce the costs of growing veggies indoors as the cost per ounce is less in a larger quantity. Although I use this product for growing veggies indoors, it would work equally well for outdoor plants. If you have an outdoor veggie garden and use the same space every year, the soil will eventually be depleted of some nutrients. The addition of this supplement in your watering could very well increase productivity and help to keep your plants healthier. If you are growing tomatoes and seeing a lot of blossom end rot, this supplement helps to producing more tomatoes without rot spots on one end. I have added pictures of some of my plants grown indoors to show you that this stuff does work. UPDATE 01/13/25: In addition to using this supplement for my tomatoes, I found out that adding it to water for veggie plants that contain calcium/magnesium increases the calcium and magnesium in the harvested greens. For example, I have started growing a variety of broccoli that produces multiple smaller heads rather than one large head. This supplement helps the plants to produce larger, stronger heads. I also use this supplement for all of my kale plants to increase the nutrients in my harvests. If you think about it, this makes sense. The plants you eat contain the nutrients they find in the soil. More calcium and other nutrients in the soil means more nutrients in the veggies you harvest. UPDATE 10/05/25: I have been using this supplement for the tomatoes and peppers that I grow indoors for about a year. I have been using it once or twice a month when my tomatoes and peppers are flowering and fruit is developing. Since using this supplement, I am seeing no blossom rot on the produce from my plants other than times I didn't water soon enough. This is a supplement I will continue using for these plants. So little is needed for watering, I am still working the the first gallon I bought, and I water a lot of tomatoes and peppers. This supplement is also beneficial to some of the other plants I grow that benefit from a little extra calcium, magnesium, and micronutrients. I hope this review was helpful for you. ## Frequently Bought Together - TPS NUTRIENTS Cal-Mag Complete, Calcium Magnesium Iron and Micronutrients Fertilizer and Supplement 8 oz (250mL) - TPS NUTRIENTS Silica Gold Plant Strength Nutrient and Supplement with Bioavailable Silicon 8 oz (250mL) - General Hydroponics pH Control Kit For A Balanced Nutrient Solution --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/618926945-cal-mag-complete-calcium-magnesium-supplement-with-micronutrients-to-correct](https://www.desertcart.vu/products/618926945-cal-mag-complete-calcium-magnesium-supplement-with-micronutrients-to-correct) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
