Review: I'm Sold! Try it - After using TPS Cal-Mag Complete, I don't think I will ever go back to traditional granular calcium nitrate again. A great blend of essential and micronutrients. This product is so superior and clean compared to traditional ones. I've noticed a remarkable difference in all of my plants, muscadine, peppers, tomatoes, and citrus trees. I typically use 1.5 tbsp of product in 4.5 gallon of water. Do not over use. It isn't necessary and could harm plant and soil balance and that wouldn't be manufactures fault. I don't write reviews but I had to brag on this product. Thanks TPS for great agricultural products. My pics aren't great and I wish I had before as well as after photos, but my garden has never been this lush. Review: Quality fertilizer. Mixed well - I have had great results from TPS nutrients. ## Features - Supports Strong Structure & Development – Helps encourage balanced growth and plant stability. - Improves Nutrient Uptake Efficiency – Supports better absorption of essential plant nutrients. - Ideal for Soil & Hydroponic Systems – Suitable for indoor plants, hydroponics, and garden use. - Made in USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CT66BTF2 | | Best Sellers Rank | #38,529 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #854 in Garden Fertilizers | | Brand | TPS NUTRIENTS | | Coverage | vegetable gardens, lawns and turf grasses, houseplants and indoor gardens | | Customer Reviews | 4.7 out of 5 stars 621 Reviews | | Item Form | Liquid | | Item Highlight | Micronutrient Blend Helps Correct Deficiencies, Soil & Hydroponics, For Tomatoes & Peppers, Helps Combat Blossom End Rot | | Liquid Volume | 8 fluid ounces | | Manufacturer | TPS Nutrients | | Model Number | TPSCMC8OZ-FBA-UPC-0124 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | TPSCMC8OZ | | Target Species | plants | | UPC | 810151951409 | | Unit Count | 8 Fluid Ounces | ## Product Details - **Brand:** TPS NUTRIENTS - **Item Form:** Liquid - **Liquid Volume:** 8 fluid ounces - **Manufacturer:** TPS Nutrients - **Number of Packs:** 1 ## Images ![Cal-Mag Complete – Calcium Magnesium Supplement for Plants, 8 oz - Image 1](https://m.media-amazon.com/images/I/71rM8twbgHL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I'm Sold! Try it *by J***M on April 27, 2024* After using TPS Cal-Mag Complete, I don't think I will ever go back to traditional granular calcium nitrate again. A great blend of essential and micronutrients. This product is so superior and clean compared to traditional ones. I've noticed a remarkable difference in all of my plants, muscadine, peppers, tomatoes, and citrus trees. I typically use 1.5 tbsp of product in 4.5 gallon of water. Do not over use. It isn't necessary and could harm plant and soil balance and that wouldn't be manufactures fault.

Mixed well *by A***R on June 16, 2026* I have had great results from TPS nutrients. ### ⭐⭐⭐⭐⭐ 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.sk/products/618926945-cal-mag-complete-calcium-magnesium-supplement-for-plants-8-oz](https://www.desertcart.sk/products/618926945-cal-mag-complete-calcium-magnesium-supplement-for-plants-8-oz) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-11-06*
