    • Great product as always
Size: 1 quart Style: Plant Supplement
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. ... show more
