Plants a pale, need help with ferts

I have noticed that my stem plants, most especially my hygro varients, have really pale leaves. In some cases they are almost white.

210 gallon tank running 200 watts of NO light
I have 20 ppm nitrate
no nitrite or amonia
dose 15 ml's of Excel daily
use root tabs in apx 2-3 inches of play sand
i do not remember my gh/kh off the top of my head but my tests ususally peg out at the top of the scale, in arizona we refer to our tap water as "liqued rock"

I have Flourish and Flourish Iron at my disposal but after a huge BBA outbreak that I finnally fought off I am very hesitant to just throw more nutrients into the system, what should I do?

Also does anyone have the nutrient defficencies picture availabe? Not the one that looks like a real plant but is more cartoony.

Is that the 6 foot long, 29 inches high, two feet front to back tank? If so, I doubt that you have enough light. A 29 inch high tank really needs T5HO lights to get enough PAR at the substrate, and with a 2 foot front to back tank, you need two of those widely spaced on top of the tank.

Jumpstart Your Plants

Hello Bones...

I have good plant growth in my low light, low tech tanks and fertilize my plants by changing half the tank water weekly and dosing a hydroponics liquid when I do the water changes.

For the more demanding plants, I use pots and organic potting soil.

Really pretty simple.

The tank is 7 feet long and only 24 inches high with 3 inches of substrate, the entire canopy is painted white and the lights are evenly spaced for complete coverage. The plants are growing its just the color that has me concerned.

I am working on creating dirt cubes from miracle gro organic potting soil and I am going to put those in the sand under my swords and crypts

I'd use the flourish again. Pale plants can often be a sign of micro deficiency in addition to co2. Given that you stopped dosing both, it may have shocked the plants too much too fast. Micros are more important than most of us think.

I went to our local plant aquarium store and picked the owners brain, he said the same thing, so I started dosing 15mls every 4 days to see if things pick up.
