Okay, algae is not bad, but plants are really bad... Completely unsure as to what is happening. The only major thing I have changed would be swapping back to liquid rock tap water, but the symptoms are not lining up...
The bottom of most stem plants, I'm talking the bottom 2"-3"-4" above the substrate are completely melting, and if the plant is only 2"-3"-4" tall... well it completely melts, and I mean completely, 0 left... complete mush:

So, what am I dosing?
Tank total volume front load:
20ppm NO3 - KNO3
5ppm PO4 - KH2PO4
12pp K - KNO3 / KH2PO4
No gH boosting - gH of tap water = 17. May need to dose 5ppm Mg... 15 degrees of the 17 is built from Ca according to API tests and rough napkin math. Okay, 5ppm shot of Mg when I get home from work today.
Fe DTPA 0.15000ppm
Now, after this week's water change and removal of the mulm, I decided to go back to some extra K. Why? well lowering it seems to work from everyone else, but because I help farmers grow corn, and corn likes to fall over when they don't get enough K (the stems get weak JUST LIKE MY PLANTS and wind snaps the stem near the base) so I matched NO3 dosing and K... We will see this week.
Going to bump CO2 as well...
All is not bad though, at least the dog and mother nature are cooperating
