Remo Magnifical is one of those products that experienced growers quietly rely on throughout every grow — not as a headline booster, but as the foundation that makes everything else work better. It’s a comprehensive micronutrient and organic acid supplement combining calcium, magnesium, iron, and a full suite of trace elements with amino acids and organic acids. The result is improved nutrient uptake, stronger cell structure, more efficient photosynthesis, and plants that handle stress far more effectively. If you’ve been running a base nutrient without a CalMag-plus product alongside it, adding Magnifical will likely be one of the most noticeable improvements you make to your programme.
What Does Remo Magnifical Do?
Magnifical works on several levels simultaneously, which is why its effects are so visible across the whole plant rather than in one specific area.
Calcium and magnesium are the backbone of the formula. Calcium is critical for cell wall structure — without adequate supply, new growth becomes deformed, tips burn, and plants become increasingly fragile as they develop. Magnesium sits at the centre of every chlorophyll molecule, meaning it’s directly responsible for how efficiently your plants photosynthesise. Deficiencies in either element are among the most common problems in indoor growing, particularly in coco and hydro systems where they’re not present in the substrate.
Beyond CalMag, Magnifical provides a full spectrum of chelated trace elements — iron, manganese, zinc, copper, boron, and molybdenum — each playing specific roles in enzyme function, nutrient transport, and cellular processes. The amino and organic acids in the formula improve uptake of all these elements by making them more available at the root-cell membrane level, while also helping to redistribute nutrients evenly from root to tip.
Remo Magnifical Dosage
Use Magnifical throughout the entire growing cycle, adjusting dose by growth stage:
- Seedling / Early Veg: Start at 0.5–1ml per litre once the first true leaves appear
- Vegetative stage: 1–2ml per litre at every watering
- Flowering stage: 2–4ml per litre — increase as the plant’s demand for calcium and magnesium rises with flower development
- Final weeks before harvest: Maintain at 2–3ml per litre; reduce in the final flush week
Start at the lower end of each range and increase based on your plants’ response. Watch for the classic signs of CalMag deficiency — interveinal yellowing of older leaves (magnesium), brown or yellow leaf tip curl (calcium) — and increase dose if either appears. In soft water areas or with RO (reverse osmosis) water, you’ll generally need to run toward the higher end of the range, as neither calcium nor magnesium is supplied by the water itself.
How to Mix Remo Magnifical
- Add Magnifical to your water before other nutrients — this allows the calcium and amino acids to dissolve fully before other compounds are introduced
- Mix thoroughly and allow to circulate before checking EC
- Add your base nutrients and other additives after Magnifical is fully dissolved
- Check and adjust pH as the final step — target 5.8–6.2 for hydro/coco, 6.0–6.5 for soil
When to Start Using Remo Magnifical
Begin Magnifical once your seedlings have established their first set of true leaves — typically around day 5–10 after germination, or immediately after rooted cuttings are transplanted. There’s no benefit in waiting longer. Early calcium supply in particular helps establish strong cell walls from the very beginning, setting up a structural foundation that benefits the plant throughout its entire life cycle.
Continue applying at every watering through to harvest. Unlike bloom-specific additives, Magnifical is a full-cycle product. Dropping it mid-grow — particularly during the transition into flowering, when calcium and magnesium demand spikes — is one of the most common causes of mid-bloom deficiency problems.
Compatible Growing Systems
Remo Magnifical is suitable for all common growing media and systems:
- Coco coir: Essential — coco contains virtually no calcium or magnesium and actively competes with CalMag uptake. Run Magnifical at the higher end of the dose range in coco
- Hydroponic systems: Critical for DWC, NFT, and recirculating systems where no media-derived minerals are available. Use with RO or soft water for best control
- Soil: Still beneficial even in nutrient-rich soils — organic acids improve uptake and distribution of native soil minerals
- Peat-based media: Peat is naturally low pH and can bind calcium — Magnifical compensates effectively
What’s Inside Remo Magnifical
The formula contains: magnesium (Mg), calcium (Ca), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), amino acids, and organic acids. All chelated for maximum plant availability across a broad pH range.
Available Sizes
Remo Magnifical is available in 500ml, 1 litre, 5 litre, and 10 litre sizes. For most home growers, the 1L bottle covers a full grow cycle easily at standard doses. The 5L and 10L options provide better value per litre for growers running larger spaces or multiple rooms.
Frequently Asked Questions
Do I need Remo Magnifical if my base nutrient contains CalMag?
Many base nutrients contain some calcium and magnesium, but rarely enough for high-demand situations — particularly in coco, with LED lighting, or when growing large, fast-developing plants. Magnifical also adds the full trace element spectrum and organic acids that most base nutrients omit. It’s worth adding even if your base has some CalMag content; just start at the lower dose range and monitor your plants’ response.
Can I use Remo Magnifical with other Remo nutrients?
Yes — Magnifical is designed to work as part of the full Remo Nutrients system alongside Remo Grow, Remo Micro, Remo Bloom, and Remo’s range of additives. It’s also compatible with nutrients from other brands.
Will Remo Magnifical raise my EC?
Yes, it contributes to overall EC — particularly at the higher bloom doses. Always check your total solution EC after mixing and before feeding. In coco and hydro, keep total EC in a range appropriate for your plant’s current growth stage.
Is Remo Magnifical suitable for outdoor growing?
Yes — Remo Magnifical is suitable for both indoor and outdoor use. For outdoor container-grown plants including tomatoes, strawberries, and peppers, apply at the vegetative dose range throughout the growing season.
