Some do, some don't, it's difficult to make a broad statement here. Pick a
specific plant to talk about.

In _GENERAL_, lower NO3 will produce more intense reds with good PO4,K, CO2,
lighting, traces, substrate.
Adding KNO3 to 10ppm or higher etc can turn many red plants green.
N stressed plants grow slower, redder generally. I'd stick with the 5-10ppm
and be careful running it lower than that. Bottoming out the NO3 can be
problematic and create many issues. I've gotten good at it without killing
or harming plants. But.........some folks will not be so lucky.
