Really appreciate the help and info, thank you very much!
I don't have a way to test potassium, but I think my nitrates and phosphates are clearly higher then potassium with the bioload and how much is fed. I am semi jumping to conclusions here thinking dosing csm+b and maybe some Epsom salt the one missing or lacking might be potassium after that.
Ya in this tank I actually have no aquarium plants only a metric pile of pothos with rainbow fish, clouded archerfish, and a bunch of filament barbs. It's a high bioload, I test nitrates regularly. With the amount of pothos in there I still need to do 40% changes weekly. Some of the pothos isn't up taking as much nitrates as it would normally but there's a ton that doesn't receive daylight and just room light and 4 hours from a current satellite pro over the pothos. In picture you can see pothos up in window but then some also goes up over curtain and down in the window as well. But everything not in a window is lush green but doesn't grow as fast.
