I'm at 45ppm is that way to high for plants to uptake. I'm noticing my Amazon Sword yellowing on a couple of leaves and a pin hole in one of the leaves. My Nitrates are at 30, GH 200 plus, Phosphates at 2-3, and Potassium as stated at 45. I don't think it would be a potash deficiency because of the high level of potash in the tank. My Melon and Flame Swords seem to be doing well. I did do a rescape last week maybe its in shock from being moved.:|

I’d be more concerned about your TDS. You have a lot of minerals in your water and it may be too salty for some plants.

Yeah, my water here in NJ is pretty much liquid rock.
