generally, is 10-15ppm nitrate good for most stem plants or should it be higher?

for those who does EI, how high does your nitrate ever get?

thanks.

10-20 ppm is generally recommended.

With EI the concentration will be twice the total weekly dosage or less, usually much less. I'm not sure what that is, but I think Nevermore has it right.
