So I have
2 x 65 PC 1 at 10,000 1 at 6500

Problem is my tank is 75 gal and 30 inches deep. When looking at Hoppy's chart I appear to be lower then low light. If I'm reading it right?

Also the tank is a Pentagon corner 24"24"30" - 36" edge to edge at the from
Pressurized C02 measuring at about 19 with a PH of 7 and KH 5.5. Drop checker is green with 4dkh solution.
Currently dosing 1 cap excel and 1 cap Aqua FLuid 7 (yes yes I will switch to dry ferts when I can actually wrap my head around EI system)

3 weeks into cycle. Everything is growing except: Amazon Swords new leafs are glassy, Micro Swords are spreading and melting at a consistent rate, some leafs on a plant which I think may be a rose sword are growing in brown. Indicia and Didiplis are really growing which is surprising because of the very low light. Onion Plants and Calamistratum are just sitting there. But hey the Java Fern and Nana are doing great :)

Also managed to get some Hair algea already and I seem to be raising a small plethora of snails.

Based on everything I see Tom post I'm guessing the issue is light or CO2 or both and because the CO2 seems in the right range I'm going with light.

So the long winded question is.

Ditch the PC lights which is the expensive piss my wife off route and get 4x24 T5 HO? or can I supplement the PC lights and with what to reach that 30" bottom?

Really just trying to get to a Medium light range. I think?

Thanks for reading this far....

Forgot to mention my NH3 NH4 is supper High about 5.0... I think do to Aquasoil and Nitrite are at about 1.6.

Did 30% water changes every day the first 2 weeks as LFS recommended for Aquasoil but slowing down now to try and get the cycle going.
A picture as of this last weekend.

Wow... nothing from no one :-(
my amazon swords melted when I first put them in my tank... They looked like how yours looks in the image. Those leaves fell apart, the new leaves started to grow in all glassy as well. They started to grow well after I put on a better light (don't laugh but at first I had a 36" 1x T8 bulb over a 48" tank, which then got upgraded to 2x48" T12 shop light). I started adding seachem excel when I upgraded to the 2x 48" T12 shop light and suddenly my amazon swords leaves started to grow in nicely. Of course the leaves never went back to looking like how yours look now. I'm not sure if the change in leaves was due to my plant being grown emmersed and then me growing is submerged or if it had something to do with the photoperiod. I changed a bunch of variables in my tank at once so I can't really do anything but guess why it went from melting to growing the way it grows now.

Also what's the deal with your substrate? what are you using? I use inert gravel. All the nutrients that my rooted plants get are from fish poop/mulm, decomposing leaf litter turned into snail poop and i guess whatever water column dosing gets to the roots through the space between the gravel.

I just googled this:

Deformed Echinodorus bleheri?

Because most if not all Echinodorus these days are grown emersed, Erik is
probably correct. However, there are commercial sellers who buy plants
from the nursery and grow their plants out underwater for a variety of
reasons. The nursery may do this themselves. So, Andy may have purchased a
swordplant with submersed leaves. Andy, there is still hope....
Some Echinodorus change the shape of their leaves in response to day lenght
(photoperiodism). These are the so-called short day plants and long day
plants... these are the ones that come from temperate and sub-tropical
latitudes. Not all plants come from the equator. In fact, many Echindorus
come from the southern part of South America or the Southern U.S. So, a
underwater plant which is grown outside during the winter in the southern
US will only be getting ~8 hours of good light. One of the Echindorus
described in the literature is E. parviflorus (black amazon swordplant).
There is also the Tropica hybrid with its hammered leaves. It is a short
day plant. Muhlberg writes: "In long day period it develops water leaves
with short petioles and rather long blades. In short-day periods the leaves
change considerably, petioles become longer and leaves more compact." This
sounds like the plant Andy described. I have not seen anything written
about bleheri and have not personally experimented with it.

Most aquarists keep their lights on for a 12-hour cycle. If you increase
the daylength from 8 to the "normal" 12 hours, the plant leaves will change
for the photo-period-sensitive plants . This is not necessarily because the
new plant is changing from emersed to submersed leaves. Even those of us
with established plants grown for a while with 12 hours might see changes
in the stem/leaf ratios when increasing to 15-16 hours of lighting. Just
another one of those unending amazements about growing aquatic plants. Who
says freshwater aquarium keeping is boring. Reefkeepers, eat your hearts out!!

Oh yea I forgot to mention. Cut off the damaged amazon sword leaves. They won't ever repair themselves and it will just grow in newer healthier leaves as you prune the damaged ones.

Substrate is

Aquasoil Power Sand M on bottom - thin layer
Aquasoil Amazonia reg - about 4 inch
Aquasoil Amazonia Powder - thin in back and denser up front -
