Sunset Hygro- Little dark spots that gradually get bigger and then
the leafs start to disinagrate... Mid to lower leafs....
On some of the others but not as predominant...

3+ WPG, DIY CO2, dosing NPK and Traces...
30-40% waters changes once per wk. always......

Could this be possibly some sort of Nutrient Deficiency :?

I have posted this type of problem before too. I think mine is green spot algae. I get it on slower growing plants and older leaves as well as inanimate things in the tank. From all the answers I have seen, this is life.

THis is just on the lower leafs on this Plant and I believe that in part
this might also be a "Shading Issue".....

The Upper and surrounding leafs all look good and have a Reddish
color as well to them...
Tank looks good in general, no algae issues......

Does it look like the problem that's currently discussed here: https://www.plantedtank.net/forum/viewtopic.php?t=6605 ?

It could well be low light. My Ludwigias do that, loose all of their leaves at the lower part of the stem, and the top looks great. Kinda natural. Pulling out, cutting and replanting helps, also ground-covering with low light plants, like Javamoss or Wisteria.

Does it seem like there is a rash of similar problems going on? I'm starting to wonder what's going on.

Aquascape? I'm a crypt farmer.

It's a fine line between fishing and standing on the shore looking like an idiot.

That IS an aquascape, it's titled "The Vacant Lot".

Maybe we are getting past the basics (I need light? What do you want me to throw into my fish tank?? I thought CO2 is bad?) and focus on more advanced issues, like sudden holes developing in leaves, even though you always fed that pleco well
