Re: [APD] P and K low level marker plants

["Giancarlo Podio" <gp at isaconsulting_com>]

Giant Hygro and Sunset Hygro are the first in my tanks to show K
deficiencies. E.Stellata and A. Gracilis are the first to show signs of P
deficiency.

Hope that helps

Do you know some plant being good  phosfate and potassium low level marker,
becuse is the first to show-up deficiencies?

For nitrate a good one is Micrantherum umbrosum
For Fe Ceratopteris cornuta (floating culture)
And for P and K?
