It would seem that as others have pointed out, NpK may be lacking. If you don't care to go the dry fert route, Easy Green or Thrive are pretty good liquids. I use Easy Green at about 1/2 the recommended dose weekly in my low tech / med light tank. I don't use CO2, but I run a bubble bar for increased O2 AND CO2.
It is common for plants to 'melt' after planting, sometimes right to nubs...but they often come back and grow well so patience is required.
I'm uncertain about your substrate (I use inert silica sand) and whether it might affect the water column. I have 'heard' here that ADA causes high ammonia in the water column and requires several high volume water changes.
As for the lights (I use the Finnex Planted+ 24/7), instead of 'Max' which is high white, you might try a custom setting of high white and high red. (With a 24" depth, I take my light out of 24/7 from 10am - 3pm and alternate between high white/red and high white/blue, then back to 24/7 for sunset/moonlight until 1am.
You might also cut back the photo period as those lights on Max for 10 hours seems like too much (and two 24/7's should be plenty)... maybe even back to six hours or so?
I envy a 180g tank (mine is a mere 60g)! Good luck and keep posting.
Tank On, Mike-
60g Marineland Community, Finnex Planted+ 24/7, Silica (pool filter) sand.
10g, 29g, & 37g fry grow out tanks, 110g stock tank.
What came first, the chicken or the egg. It was the egg, but not the egg from a chicken.
