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?

Hi Philosophos,
I just remembered that I have some crushed corals in my filter. (That could be why for the high Ca level) My LFS recommended me to add some crushed corals because my Ph was kind of low when I was cycling my tank. But anyways, I am not totally sure if my No3 is correct. I tried to calibrate the test kit with a known No3 value but the color does not match up with the card. I even went to the extremes to test the kit using less than 2oz of r/o water with 1/4 tsp of KNo3 and the test shows 10ppm. So I don't know if I can trust my No3 numbers. As for K+ I am using K2SO4.
But here is my setup:
Tank: 29g show tank connected to a 20g holding tank with 20g diy sump (total volume of water is around 50g with about 3in of eco-complete in both 29 and 20)
Heater: 300w stealth heater
Light: 36" 4x39w T5 hang at 8in. above the 29g
Bulb: 2 midday, 1 aquaflora and 1 power grow (had two aquaflora before but the tank is yellow looking so I switch one out)
Co2: 25lb pressurized with diy reactor.
Routine:
Light: On from 12-3 and 5-10
Dosage: 5ml pps pro and 5ml csm+b everyday
Co2 level: I have a drop checker with 4dkh solution which seems to stay at blue-green color even though my bubble counter is at about 15bps.
WC once every two weeks
If you need more info about the set up please ask.
Thanks
