Calnesium 2-0-0 is a nutrient additive that will boost both Calcium and Magnesium availability to your plants when added to your feed program.
It is a powerful blend of Nitrogen, Calcium, and Magnesium that is specifically designed to provide an additional nutrient boost to our Future Harvest Holland Secret 3 Part fertilizer for crops that demand it. It is an excellent additive to prevent end rot on tomatoes and peppers.
Calnesium is 100% compatible with all high quality nutrients as it mixes quickly and easily. Calcium, Magnesium, and Iron are incredibly important to photosynthesis (making energy from light) and maintaining the structure of the plant. Calnesium works as part of your feed program and as a foliar spray.

QUESTIONS & ANSWERSAsk a Question
How much Ppms should 200ml in a 100liter Rez add ? It feels like it goes up a lot for the Amount used of the product.
Hello. Thanks for reaching out to us.
By itself Calnesium will raise ppm by 320 at 2ml/l.
Keep in mind that mixing it with other fertilizers will
have a significant impact on this number since the
other salts can increase or decrease the conductivity of the solution.
Hi There, why are you not able to use calnesium in the transplant stage?
Hey Olivia, technically you could use Calnesium during the transplant stage, your plants would be fine.
However if your plant is quite young we would recommend taking caution in adding too much ppm with the Calnesium.
We just recommend it during early flower as that is when it will require it the most.
So wen I mix I only use 2 ml per litre right doesn’t seem like it’s a lot so I was just wondering
Hey Jordy, hope you are having a good day.
Our current calculator is recommending 1.5ml of Calnesium per 4L of water while your plant is in Veg growth.
Once you flip your plants you could then bump the dosage of Calnesium to 2.5ml per 4L for the first 2 weeks of flower, followed by 5ml per 4L of water at week 3 of flower.
( please note this is for soil / coco, not Hydro feeding dosages )
As the plant flowers it will want more Cal Mag and that is when Calnesium truly shines. Prior to that it is an essential nutrient recommended through out its life cycle.
If you have anymore questions please let me now.
The label says " WARNING: Never combine the nutrients full strength. This can cause lock up. What does that mean? Do I lower my nutrient strength to 1/2 and use calnesium full strength?, or dont use calnesium at full strength? This is very confusing, I bought it on the recomendation of the shop keeper. I went there for calmag, he said this was better.
Hello! What we mean by not mixing the nutrients full strength, you should always have a resivour with water to mix the nutrients. You don't want to mix the nutrients and addivties together in a small cup(without water) then pour it into the resivour.
If you are confused on our feeding dosages please look to our nutrient calculator on our website.
Going 1/4 strength is great for foliar spraying only or bare miminum feeding.
Every feed/dosage should follow our calculator for best results.
This is the same for calnesium
