What's the KH?
Leave the peat moss out unless you add it to the gravel, you don't need it
for the plants.

Why peat, Excel, CO2 fizz factory and DIY CO2?
I'll say this once : Cut it out.
Use only CO2 gas to manipulate your pH. And use only one system.

Well, light, traces etc are not the problem so what do you think the odds
are it's CO2? All that iron will do no good if there's not enough CO2. Same
for the light.

Well this will simply make your bad problem worse.

Now you can _fix_ things with that. This is your main area to work on and
focus on. Get this right, then add the other lights etc.
With that much light, you'll need KNO3, K2SO4, PO4 and good CO2.

No, no and no.

Again. no, no and no. It's going to make the issue more complicated. There's
an extremely tiny chance, less than 0.5% that the copper is high in the tap,
see if it's over .2mg/l (ppm) or higher etc. That's should be clearly
Stop messing with the pH with 4 things, say what the tap water's KH is,
All you do is check the pH/KH/CO2 chart then and see what pH you need for a
CO2 level of 20-30ppm. Add enough CO2 gas ONLY to do that. That's all there
is to it.
Regular water changes, light, add nutrients(such as PO4, NO3 and K along
with the traces) and make sure you have a good level of CO2 during the
entire time the lights are on. Swords are weeds.
The rest of the tank checks out: good light, traces, substrate, filters, all
you need to work on is regular water changes, macro nutrients, NO3, PO4 and
K and then the CO2 issue.
