title says it all
I am a planting idiot so take my advice with a pinch of salt, but I think the general rule is you only need TNC Complete (which inlcludes N & P) if you are adding C02 or Carbon. You probabaly only need TNC 'lite' if you are not doing so
......now please wait for someone with any clue about plants to back up my comments.
