 Re: Ca and Mg help!
Your Ca and Mg are very high. So high that I wouldn't worry about it, unless your Ca is coming from CaCO3. I see something else off here, without a doubt; your NO3 is low, your PO4 high. If you increase PO4 levels high enough, NO3 uptake will increase. Once you dose enough NO3, I'm willing to bet that your red plants will turn green.
Also, look at your CO2... odds are you don't have enough of it. Right now, it's an extremely typical problem in the hobby given all the over-watted light around. A lack of CO2 looks stunningly like a lack of Ca in some ways, given that both are vital for plant structure.
What's going on for dosing with your K+? Also, what're your hardware specs with regards to lighting, column volume, and CO2?
