Mostly just curious. When mixing nutrients, should calmag come before or after the base nutrients? I googled this a while and see it both ways. So far I’ve been using this sequence:
1. Silica
2. Base nutrients (NPK)
3. CalMag
4. Trace minerals
5. ph adjustment, if necessary
I don’t seem to have a problem. I start with a 5 gallon bottle of ro water with an air stone and allow each of these to sit for 15 minutes aerating before adding the next one. I see no precipitation or gelling. I use immediately after mixing.
The only questionable thing here is should base nutrients and calmag be swapped? In various forums I can find specific instructions each way. Since I’m not having any problems I suspect it really doesn’t matter much, but is there a definitive best practice?
Does this depend on the calmag sources? If the magnesium in calmag comes from epsom salt, I can get precipitate from the sulfur ion. My magnesium comes from magnesium chloride, so I don’t have that problem. Does this just side-step the ordering issue?
Silica, pH up, Jacks, auto mix in 1qt, pour into 2 gallon sprayer, consistent 1600 and 6.0 with our well water. My meter broke in December and i winged it for 2 months. New meter same numbers.
