FloraMax Ca-Mg-Fe Powder
Chasing a deficiency one element at a time is slow work. FloraMax Ca-Mg-Fe Powder is a concentrated deficiency corrector that puts calcium, magnesium and iron back into the feed, together with copper, manganese, zinc, molybdenum, boron and nitrogen. FloraMax call it their ultimate Cal-Mag additive. Their reasoning is that the common deficiencies growers chase come from these nine elements, never from calcium and magnesium alone.
That's why Ca-Mg-Fe carries all nine. Several of those shortages look alike on the leaf, and pale or yellowing foliage can point to nitrogen, magnesium, iron or manganese running short. A product that tops up only two nutrients leaves you guessing which one it was. Ca-Mg-Fe covers the whole group in one addition and brings the feed back into balance without you working through the elements one by one.
It's a corrector, not a constant. In both the FloraMax VegaFlora and Veg-1 programmes, Ca-Mg-Fe sits outside the regular weekly schedule as an optional additive, used only if required. It's there for when a crop shows a shortfall, not for every tank. While a deficiency is being corrected, the crop is fed more often and given generous run-off.
Ca-Mg-Fe comes as a dry ProPowder. You can weigh it straight into the reservoir, or dissolve it into a liquid stock concentrate first and dose from that. Dissolved, it goes a long way! A 200 g bag makes 1 L of stock, enough for about 660 L of working nutrient solution. The 1 kg and 4 kg bags scale that up to 5 L and 20 L of stock, good for roughly 3.3 kL and 13.3 kL.
Every dose of this powder is weighed, so the one piece of kit worth sorting before your first batch is a set of scales that reads to 0.1 g. A loose powder settles differently each time, which means a scoop won't hold the same weight from one fill to the next. For reservoirs from 10 L to 1,000 L, a scale with 3 kg capacity and 0.1 g resolution suits Ca-Mg-Fe.
The powders don't spread evenly through it, so the whole pre-mix belongs in a single nutrient batch, never split across several.
Nine elements in one powder, because deficiencies are never just Cal-Mag!

Directions for Use
Application Rate
- Hydroponics: 0.3 - 0.6 g/L
Application
- Fill the reservoir with water first, then weigh the powder on scales rather than measuring it by volume.
- Add Ca-Mg-Fe only when correcting a deficiency, and stir well after every addition.
- While correcting, feed more often and ensure 10-15% run-off.
- Maintain a final pH between 5.0 and 6.3.
- It can be combined with other FloraMax ProPowders as a dry pre-mix. The blend is not homogeneous, so allocate the entire pre-mix to one nutrient batch.
- Dose at 0.3 - 0.6 g/L (ProPowder) or 1-2 mL/L (Liquid), as required during the vegetative and flowering stages.
Safety
Keep air-tight, away from direct sunlight, preferably below 25 C (77 F).
