Probably. New leaves should be paler (a light green) than existing leaves, but transparent is getting too pale if you mean when the leaf is a decent size. Echinodorus are heavy feeders. Plant nutrients occur from many sources: tap water (via the water change), fish foods, decomposing organics. All of these will vary from tank to tank. Generally speaking, Flourish Comprehensive Supplement dosed once or twice a week will supplement most tanks that are setup as natural or low-tech. Using substrate fertilizers (tabs) esp with heavy feeding swords is probably better than dosing Flourish Comp twice. I have experimented with this, and found I had less other issues with Flourish Comp once a week [as opposed to twice], when I used Flourish Tabs next to the larger swords (one tab per plant).
You can buy Flourish tabs online; probably less expensive than in a fish store too [it is for me]. There are ten tabs in a package, and you need one per large sword plant; they must be replaced every 3 months (according to Seachem).
