Review: Great product as always - I recently added Botanicare Cal-Mag Plus to my plant care routine, and I’m really impressed with the results. The product arrived promptly and was excellently packaged, with no leaks or damage to the bottle, which is always a relief when ordering liquid supplements. From the first use, it was clear that this supplement was high quality. It’s easy to measure and mix with my regular nutrient solution. I started using it a few weeks ago, and my plants have shown significant improvement in their overall health and vigor. Cal-Mag Plus is fantastic for addressing common deficiencies in calcium and magnesium, which are crucial for plant growth. Since incorporating it into my routine, I’ve noticed my plants’ leaves are greener and more robust. There are no more signs of yellowing or other deficiency-related issues. This has been particularly beneficial for my tomatoes and peppers, which are heavy feeders and often prone to such deficiencies. Another great aspect of Cal-Mag Plus is its versatility. I use it for both my soil and hydroponic plants, and it integrates seamlessly with my existing nutrient regimen. It doesn’t cause any imbalances or issues, which makes it very convenient. I’ve also observed that my plants are more resilient to stress since I started using this supplement. They seem to handle fluctuations in temperature and light better, and their overall growth has been more vigorous. The added iron in the formula is a nice bonus, contributing to better chlorophyll production and healthier plants. Overall, I’m extremely satisfied with Botanicare Cal-Mag Plus. It’s a reliable, high-quality supplement that has made a noticeable difference in my plants’ health. If you’re dealing with calcium or magnesium deficiencies, or just want to ensure your plants have everything they need to thrive, I highly recommend giving this product a try. It’s become an essential part of my plant care routine, and I’m excited to see continued improvements as I keep using it.

## Questions & Answers

**Q: How much will this make?**
A: Mixed at 3ml per gallon it will make 320 gallons.
Mixed at 5ml per gallon it will make 192 gallons.

**Q: Is this carbonate based?**
A: Near neutral pH, ferric ions form insoluble solids and are thus not bioavailable. EDTA (and other chelating agents) address this problem, by forming soluble complexes that resist formation of hydroxides. EDTA increases the bioavailability and plant uptake of the metals in the soil

**Q: How long can this be kept and or stored**
A: Product warranty on nutrients and supplements is 1 year past the date of manufacture. Stable shelf life can run past this substantially if unopened, but this time greatly depends on storage conditions. Once a product is opened, it should be used within 6 months, or ideally- the time it takes to cycle a production garden which is typically 12 weeks on average. Opened products may last longer than this, but it should not be expected to be the case.

**Q: Can this be used for Tomatoes, Blossom end rot?**
A: Yes, this works well with Tomatoes.

Just the right supplement I needed. Solved my growing problems.

### ⭐⭐⭐⭐⭐ Good mix for your grow
*by F***S on November 23, 2025*

You can do without a lot of what they sell to indoor growers. This, like a good fertilizer, is imperative. Bottle was well sealed with no leakage. I use 50ml plastic syringes (no needle) to get an exact mix. I've been using this for years and see no reason to quit.
