Calimagic 1-0-0! I know there's other products aswell and someone can probably add to the list of Ca/Mg products with no to very little nitrogen.
I do add calmag. A good bit. There is the Remo MagNifiCal (their calmag) which I use currently at 8 ml/gallon (by the Remo chart) and I’m at 1/2 tbsp (7.39 ml) per gallon added on top of that of my own. Most folks would think this is way overdoing the calmag. You can clearly see from my grow it is not. Not only does coco leach it a lot, autos also use it more under LED than photos. That much is what is required. And as you have also seen both now and in the past, my calmag usage results in the fact that I almost never have deficiencies or plants out of green. Anyway, that’s just what I do.Forgive my ignorance but aren’t you supposed to add cal-mag with hydro? Or is that only something with coco? CL
I agree @Wastei - I discontinue all calmag usage as of week six(ish) of flower and only if required do I ever pull it back out. That’s a great point and a very very common mistake, using calmag to the end.
You must add cal mag to every feed you ever give the plant, which is daily, in coco. It’s an inert medium. The plant only eats what you give it in coco. Calmag is 100% required every feed. I learned that from the master, @Bill284.I grow with soil although I have been told that I should switch to coco. But I’m still curious about other methods of growing hence the question. CL
I'm not most people! I don't how ours compare as different products but we're at 2.5ml/L of 4-0-0 Fe Loads of the stuff.
Imho, you don’t need another product, just discontinue calmag or your 4-0-0 stuff around week six. That is what I’d do.
About the same. I’m using 2-0-0 Humboldt’s Secret CalMag plus Iron as the extra and I believe the Remo is 3-0-0. Pretty much the same thing.
Calimagic eh? I’ve been looking for a 1-0-0. Mine is 2-0-0. Still pretty low.
Is that a question for me? Not sure I understand the question. Could you please clarify for my stupid high brain? Lol. Thanks.
I get you but cal mag is not supplier specific just Nx -0 -0 i could feed less I guess but I don’t want so much N - I do want the flower. At some point the fans need to go and chlorophyl is the enemy when it comes to cure.
I'll add TPS calmag to the list of 0-0-0 versions. Available on Amazon here in the States.
Coco retains rather than leaches calcium and magnesium. That's why coco growers add more.
Thanks for the input! The organic version they sell is however not recommended to be used as a pH buffering agent in hydro where nitrate based and carbonate based still has its place.
I'm not aware of any hydro growers using calmag to regulate their pH, but if those folks are out there then indeed there is nothing in 0-0-0 that will have any effect on the pH of the solution.
