Just wondering if anyone adds these as beneficial micros in hydroponics? The sodium is probable already present in whatever nutrient solution, I imagine Cobalt and Nickle would only be used at a very low rate, 0.1 to 1.0 ppm.. anyone bother messing around with these? Probably never make a difference anyways who knows lol

Hi,

Cl is essential for all plants, although at a very micro amount.
Na is not beneficial for Cannabis, as is Cobalt (its usefull for fruiting plants that develop Vit B12)

I add a basic micro nutrient blend. It's all the plant needs. I don't know why the hell you'd need to add cobalt.


This has everything needed as far as micro's.

Its considered an essential, I believe it's like number 17 on the list.. It's likely already included as an impurity from other salts..

Exactly. There is enough present as impurities already present. Too much can be harmful so adding more could be detrimental to plant growth.
