Calcuim Defeciency?

[matthewburk]

I "think" I may have a calcuim defeciency, but my GH is 30 degrees, is that possible?

I am basing this off the description here http://www.csd.net/~cgadd/aqua/art_plant_nutrient.htm

What I am seeing is my ludwiga leaves very curled up and my crrypt balansae looks good, but I get 2 or 3 new melting leaves every day. Also my cardamine iryata has reddish leaves, looks nice, but doesn't seem normal.

It's getting worse, my creepying jenny (old) leaves are tuning dark green in areas and look like they are dying, it is a slightly translucent apperance.

CO2, it's not Ca, try more traces also.

I does 1/4 teaspoon of CSMB with Iron 3 days each week, its a 90 gallon tank. Should I increase that to 1/2 teaspoon?
