What's your NO3? Are the leaves melting anywhere etc? It does sound like NO3
to me. Whitish color and poor growth on fast growers. The sword is getting
more food and has more roots to get anything in the substrate that might not
be available(or as available) to the Hygro etc. How hard is the water? GH?
A water change and some GH and KNO3 would most likely "cure" it. Ca is
immobile and would produce some of what your seeing and the NO3 could also.
Are you adding a fair amount of traces? You may need more. ??So if you go
down the line, NO3?, Ca?->GH, and traces? Somewhere in there lies your
answer most likely.
