Hi @Jackbrew,
Welcome to TPT!
I looked at your pictures and your dosing levels. You are only dosing about 2.2 ppm of nitrogen per week (2 X 2 ml) and likely under-dosing the other nutrients as well. I would start by increasing dosing of all nutrients except Seachem Excel to double your current level and see if you can obtain 10.0 ppm of nitrates with your test kit. Keep the tank at this level for two weeks and see if the plants show a positive response with greener color and better growth.
The broadleaf watersprite (Ceratopteris cornuta) in your tank is showing physical damage, not a nutrient issue. I suspect the plecostomus are enjoying a salad, especially after the lights go out. I don't use plecos in my tanks specifically because they seem to enjoy my plants as much as I do. For algae control I use Siamese (not Chinese) Algae Eaters (Crossocheilus oblongus) and Otocinclus which don't damage my plants.
Let us know how things go! -Roy
