Why Choose Technaflora MagiCal
MagiCal is a highly enriched, formulated blend of magnesium, calcium and iron built to be added to a regular fertilization program. Rather than replacing your base nutrient, it tops up the three elements that gardens most often run short of — calcium and magnesium, with iron alongside — so the rest of your feed can do its job. The result is more vigorous plant growth, support for protein synthesis, and the kind of healthy cellular structure that translates into better yields.
Two qualities make MagiCal easy to live with. First, it is extremely concentrated, highly soluble and chemically stable, so a measured dose goes a long way and the product holds up in storage and in solution. Second, it is completely soluble and clear of any sediment, which means it mixes with ease into any solution and provides an instantly available source of the nutrients your plants are asking for — no settling, no clogging, no waiting.
Because it was formulated as a universal supplement, MagiCal works in conjunction with any premium brand of nutrient. You do not have to abandon a feeding schedule you already trust; you simply add MagiCal to correct calcium- and magnesium-related deficiencies as they appear. Growers reach for it to rapidly correct Ca and Mg deficiencies, to create lush and greener foliage, to improve the yield of fruit, and to help maintain a vigorous root system across the crop cycle.
Best Uses for Technaflora MagiCal
MagiCal is a supplement, not a standalone diet, so it shines wherever a base feed needs reinforcing on calcium and magnesium. The most common scenarios are:
- Correcting deficiencies — gardens are often deficient in magnesium and calcium, and supplementation may be precisely what your plants need. MagiCal is built to rapidly correct Ca and Mg nutrient-related deficiencies as they show up in new growth.
- Boosting growth and vigour — the blend promotes vigorous plant growth, supports protein synthesis and helps maintain a high starch content in crops, enhancing the growth and vigour of leaves, flowers and fruit.
- Improving yield and foliage — by improving cellular structure it increases overall crop yield, while creating the lush, greener foliage growers associate with a well-fed plant.
- Strengthening roots — MagiCal helps maintain a vigorous root system, which underpins everything that happens above the medium.
Because it is suitable for hydroponic, soil and soilless gardens alike, MagiCal fits equally well on a recirculating reservoir, in a coco or peat container mix, or in a traditional soil bed. Growers building out an additive shelf often run it alongside carbohydrate and microbial products such as Earth Juice Hi-Brix molasses to round out a feeding program.
Compatibility
One of MagiCal’s defining strengths is how easily it drops into an existing routine. It is a great supplement that is easily added to a regular fertilization program, and because it is extremely concentrated, highly soluble and chemically stable, it works in conjunction with any premium brand of nutrient. You are not locked into a single nutrient line — MagiCal is designed to complement whatever base feed you already run.
The fully soluble, sediment-free formula suits the full range of growing methods: deep water culture, ebb and flow, drip and run-to-waste systems, as well as coco, soilless mixes and conventional soil. It dilutes cleanly into reservoir or feed water and stays in solution, so it will not foul lines or leave residue in the tank.
On a typical additive shelf, MagiCal pairs naturally with beneficial-microbe inoculants such as Advanced Nutrients Tarantula and broad-spectrum plant products like PureCrop1. As with any change to a feeding program, introduce a new supplement gradually and watch how your plants respond, since every water source and system behaves a little differently.
Dosing & Mixing Guidelines
MagiCal is an addition to your regular feeding program rather than a replacement for your base nutrient, so the goal is to supplement — not overwhelm — the calcium and magnesium your plants are already receiving. The label on your bottle carries the authoritative mixing rates for your specific formulation and crop; always follow them. The general good-practice notes below apply when working with a concentrated Cal-Mag supplement like this one:
- Read the label first. The dosing instructions printed on the MagiCal bottle are your baseline — use them rather than a generic rate.
- Add to water, then mix. Because the formula is completely soluble and clear of sediment, it mixes with ease; add it to your reservoir or feed water and stir to disperse it fully before feeding.
- Add supplements separately. When combining MagiCal with a base nutrient, add each product to the solution separately and stir between additions rather than mixing concentrates directly together.
- Start conservative. The blend is extremely concentrated, so begin at the lower end of the recommended range and adjust upward only as your plants’ response and your deficiency symptoms indicate.
- Monitor your solution. Check reservoir strength and pH to your system’s usual targets after mixing, and correct as needed.
Specific millilitre-per-litre rates are not reproduced here because they belong to the product label and can change between formulations — refer to the instructions printed on your bottle for exact figures.
How to Correct Calcium and Magnesium Deficiencies
Calcium and magnesium deficiencies are among the most common problems growers run into, and they often appear together. Magnesium shortage typically shows as yellowing between the veins of older, lower leaves, while calcium shortage tends to distort and damage new growth at the tips. Because gardens are frequently deficient in both, a targeted Cal-Mag supplement is often exactly what the plant needs to recover.
MagiCal is formulated to address this directly: it provides an instantly available source of magnesium, calcium and iron, and is built to rapidly correct Ca and Mg nutrient-related deficiencies. When you spot the symptoms, add MagiCal to your regular feed at the label rate, keep your solution within normal pH and strength windows so the nutrients stay available to the roots, and give the plant time to push out healthy new growth. As the deficiency clears, you should see the return of lush, greener foliage and renewed vigour through the leaves, flowers and root system. Continue supplementing as part of your routine to keep calcium and magnesium from running short again later in the crop.
