Re: [GSAS-Member] Plants Wasting Away

Strangely enough it could be a deficiency of Nitrogen. If you aren't adding 
Nitrogen,
and you ARE adding CO2, and the algae is growing fast - it might be grabbing up 
all the
nitrogenous compounds before the plants do. Sometimes you can use a solid 
fertilizer at
the base of selected plants to test that hypothesis. Are there very many fish 
in there?


On the other hand, I've heard that lack of calcium can cause brown spots on 
swordplants
and some others. Maybe I'm wrong about that because when I try adding calcium it
doesn't seem to help.
