Sword leaves turning brown/yellow reddish w/holes

Pretty much like the title says. I have root tablets near the plant plus dose flourish twice a week. So I am not sure what else to do. The plant shot off like crazy when I change the substrate but now it seems to slow down and the leaves started turning colors. Any thoughts?
I have a pic but is a really bad pic cause I took it quick on my way out the door to work.

There can be several reasons. Yellowing in general can be light or nutrient-related; plus as redchigh is suggesting the older leaves especially after moving the plant.

The brown spots are probably iron deposits. My swords are doing somewhat the same. In my case I have ascertained it is an excess of iron, caused by a deficiency of calcium, due to my soft water. When I had dolomite in the filters, this didn't occur, or very minimally; but the dolomite after 12 years is exhausted (I assume) and this condition rapidly occurred last year to the extent that I finally had to pull all the plants and remove all existing leaves to allow them to re-grow. I haven't beeen able to get dolomite locally, so I'm now using aragonite as of 2 weeks ago which should add some calcium.

Do you know your water hardness (GH)?

Byron.

I will also say this the outter leaves have never seemed to get any bigger but the inner leaves are the ones that shot off like crazy. They are to the top of the water line and are floating a little. They grew crazy tall while the outer leaves barely grew any. Also the inner leaves are the ones showing the discoloration.

That is more worrying. The inner leaves are of course the newer.

A GH of 10 should provide sufficient calcium. Plus there is a bit in the Flourish products [though not sufficient without some in the tap water, which is my problem].

On the root tabs, are they Flourish tabs? And just one within 5 inches of each plant, or more?
