I asked the question because I thought I saw some nutrient deficiency in the swords. While iron is an important nutrient for swords, so are the other 16 and a deficiency of any one of several can look the same. I do not use iron alone, I did once years ago and the excess iron caused more trouble. Nutrients have to be balanced. My recommendations from experience are Seachem's Flourish Comprehensive Supplement for the Planted Aquarium
and Kent Freshwater Supplement. I have used both with success, and these two contain all the necessary nutrients in the required proportion. Once a week to start, after the partial water change. Monitor the plants for 2-3 weeks, and if the swords in particular are not sprouting lush green coloured leaves (the new leaves, the existing leaves will not improve) do a second dose 3 days after the first. I need to do this to maintain my swords and the floating frogbit in the 90g.
In addition, a substrate fertilizer for the swords will result in astounding growth. Flourish tabs are OK, but I prefer Nutrafin's Plant-Gro sticks because they are cheaper, last a year, and after 2 or 3 months the swords that had them doubled in size and new leaves have continued to sprout for months now. I reduced the liquid to once a week at the same time, thinking maybe not necessary, but nope, leaves looked a bit peaked so back to twice a week.
Just for fun, here is a photo I took a few minutes ago of my 115g showing the increased growth since the last photos (under my "Aquariums"). The two Echinodorus bleheri at the back are now up to the surface; the E. macrophyllus on the far left (the sword with long stems and 7-inch floating leaves) is more than 10 years old, and there are two daughter plants from the flower spike it produced this past summer. One is now up to the surface (3 months) and is just right of centre.
