A few things that are bugging me! (glosso & plants)

There is two things I want to achieve, and I can't do either.

First thing, is my plants are not turning red. Despite the amount of iron I dose, and the flourite red, and eco complete I use as a substrate. The plants are healthy, but not red, they are all just, very green. A couple DO turn red (l.repens) but my l.aromatica stays a lush green, r. macrandra stays green, sunset hygro, and pogostemon E., also green.

Also, my glosso that I planted about 4-5 weeks ago has not moved an inch. Doesn't grow out, doesn't grow up, just stays where I planted it. I would figure with my tank parameters it would of covered the whole ground by now, but it stays perfectly still.

My tank parameters:

55 gallon
Lighting: 3.5WPG on 10 hour cycle, with 1 hour siesta mid-day. Lights are approx 8" away. Bulbs are about 4 months old.

CO2: 1.5-2BPS - 100% Diffusion through CO2 Reactor through out take of filter. CO2 turns off when lights go out, then air stone runs at night. No, I don't have a drop checker.

Filter media: 4 Polishing sponges, 2 regular sponges - removed ceramic yesterday

Substrate: Flourite red capped with eco complete

EI Dosing:

24.76ppm (1/2tsp - 8.4g) KNO3 3x weekly
2.35ppm (1/8tsp - 0.70g) KH2P04 3x weekly
1.51ppm (1/8tsp - 0.70g) K2S04 3x weekly
1/8tsp - 0.70g Trace (CSM+B) elements 3x weekly

50% weekly w/c
GH boost during w/c
Cal: 23ppm
MgS04-7H20: 2.5ppm

NO3: 10
NO2: 0
Am: 0
pH: 6.0-6.5
GH: ?
KH: ?
Temp: 24-28C

Any thoughts would be great.

What kind of lights? I would up the CO2 to 2-3bps off the bat(depending on what type of lights you are using at 3.4WPG). Are you dosing any additional iron besides the CSM+B?

how far away are the lights from the plants you wish to turn red? I have found that my ludwiga turns red when it hits the upper half of my tank.

not that far away, give or take 5" - it can't go any higher than that due to my sloped ceilings where the tank is located.

The lights are 2x 96w CF

I was dosing flourish iron, but recently turned to csm+b to try something different. I thought the amount of iron in the flourite, eco complete, trace, and the Iron-DTPA in the GH Boost would be enough!

I'm going to see how the plants do this week. I've been keeping a log of everything I do and change in the tank. I'm going to run out the rest of the week with some new elements I added (barr's gh boost) and then next week I'll up the CO2 to 2-3bps for a week. If no changes are reported, I'll keep the CO2 at that and add the extra iron.

With a 55g it may be difficult getting light to penetrate all the way down to the glosso. That is the key with glosso - if it gets enough light it will run and grow well without much influence. With a deep tank I like to find the "hot spots" where light reflects off the glass unto the substrate for a higher PAR. This is where I would plant ground covers which have increased light demand.
