Customer Questions & Answers
-
Question:
What are the main benefits of using Organic Cal-Mag OAC Plant Nutrient and Supplement?
Answer: The Organic Cal-Mag OAC supplement provides essential calcium and magnesium for plants, crucial for their growth and nutrient absorption. Calcium strengthens cell walls, improving the plant's structural integrity, while magnesium plays a vital role in photosynthesis. This combination helps enhance the overall health of plants, leading to better yield quality and resilience against diseases and pests. Whether you’re growing fruits, vegetables, or ornamental plants, incorporating this nutrient can significantly bolster plant vitality. -
Question:
How do I use Organic Cal-Mag OAC in my gardening routine?
Answer: Using Organic Cal-Mag OAC is straightforward. Dilute the recommended amount in water and apply it either as a soil drench or a foliar spray. This method allows for efficient nutrient uptake by the roots or leaves. It's ideal to apply it during the vegetative and flowering stages of plant growth, ensuring that your plants receive the vital nutrients they need for optimal development. For instance, using it alongside a regular watering schedule can enhance nutrient absorption and support lush growth. -
Question:
Is Organic Cal-Mag OAC safe for all types of plants?
Answer: Yes, Organic Cal-Mag OAC is formulated to be safe for a wide range of plants, including fruits, vegetables, and ornamental varieties. Its organic composition ensures that it’s gentle on plants while providing them with essential nutrients. However, it's always wise to test a small area before widespread application, particularly with sensitive plants. Many gardeners find it effective for preventing deficiency symptoms in crops like tomatoes and peppers, facilitating robust growth and fruiting. -
Question:
What should I look for in a high-quality Cal-Mag supplement?
Answer: When choosing a Cal-Mag supplement, opt for one that is organic and contains additional micronutrients, as these support plant health comprehensively. Look for products that indicate their calcium and magnesium percentages clearly and include beneficial trace elements like iron and zinc. High-quality supplements, like Organic Cal-Mag OAC, can help prevent nutrient deficiencies and promote overall growth. Additionally, reading customer reviews can provide insights into the product's effectiveness in various plants. -
Question:
Can Organic Cal-Mag OAC help with blossom end rot in tomatoes?
Answer: Yes, using Organic Cal-Mag OAC can help alleviate blossom end rot, a common issue in tomatoes caused by calcium deficiency. By ensuring your plants receive adequate calcium, this supplement can promote stronger fruits and reduce the risk of this physiological disorder. Applying it at the onset of flowering can be particularly beneficial, as it supports fruit development and overall health. Gardeners have reported significant improvements in fruit quality and yield when using Cal-Mag products. -
Question:
How often should I apply Organic Cal-Mag OAC during the growing season?
Answer: For optimal results, apply Organic Cal-Mag OAC every two weeks during the growing season. This regularity ensures that plants continuously receive the necessary calcium and magnesium, especially when they are actively growing and developing fruits or flowers. Adjust the frequency based on your plant species and growth stage; for instance, during heavy fruiting, a weekly application may be advantageous. Monitoring plant health can guide adjustments to your feeding schedule. -
Question:
Are there any specific storage instructions for Organic Cal-Mag OAC?
Answer: Store Organic Cal-Mag OAC in a cool, dry place away from direct sunlight to preserve its efficacy. Ensure the lid is tightly sealed after use to prevent contamination and moisture intrusion, which can degrade the product over time. Keeping the nutrient protected allows you to maximize its shelf life and effectiveness, providing a reliable resource whenever your plants need that extra boost during their growth phases. -
Question:
Can I combine Organic Cal-Mag OAC with other fertilizers?
Answer: Yes, Organic Cal-Mag OAC can be mixed with other fertilizers, provided they are compatible. This supplement can enhance the effectiveness of nutrient blends, as it delivers essential calcium and magnesium. However, avoid mixing it with products containing high levels of phosphorus, as this can interfere with calcium uptake. Using it in conjunction with balanced fertilizers can lead to improved plant nutrition and growth. Gardeners often find success by experimenting with different combinations to suit their specific plant needs. -
Question:
Is Organic Cal-Mag OAC suitable for hydroponic systems?
Answer: Absolutely, Organic Cal-Mag OAC is suitable for hydroponic systems. It provides a rich source of calcium and magnesium, both of which are crucial for plant development in soil-less environments. When using it in hydroponics, ensure proper dilution in your nutrient solution to maintain the appropriate balance of minerals. Many hydroponic gardeners find that this supplement significantly enhances plant vigor and yield, especially during critical growth stages like flowering and fruiting. -

TPS NUTRIENTS Fertilizers & Plant Food TPSCMOAC1Q-FBA-UPC-0523 Editorial Review
The TPS Nutrients Organic Cal-Mag OAC is an effective plant nutrient supplement that is vegan and gets absorbed easily. It is made up of a highly pure organic source of magnesium carbonate and calcium hydroxide, which are micro-chelated via a plant extract package and finally combined with a proprietary blend of three organic acids. As it doesn't contain any nitrates, it won't show up on PPM meters, and when used in conjunction with slow-release organic fertilizers, there should be no residues that need flushing, as microbes break it down. If used at a higher concentration, it might work as an alternative to lime in correcting low pH levels. With heavy metal analysis tested below all national standards for dangerous heavy metals, it also contains no animal products. TPS Nutrients recommends using no more than 5mL per gallon with compost tea.
