OK, hope these answers help (here it goes)!
Echinodorus tennellus needs high light, CO2, and a rich substrate to grow. Adding fertalizer spikes would not help. I would reccomend you get some higher lighting first. For a 10 gallon, it shouldn't be too expensive. Right now, since you only have 1 plant and low light, you shouldn't be adding any fertalizer of any type. You really didn't say what your lighting was, but it should be around 30 watts, and not much less, if you want your chain sword to grow. The liquid fertalizer would help any plant grow in given conditions. You shouldn't be using hagen plant grow, so don't monitor for iron. A stem plant is a plant with stems (??). It mainly takes in nutrients from the water collumn instead of the substrate.
All this is regarding you want to grow the one plant you have now. It is (very) possible to do a planted tank without Co2, or highlighting, but the plants will grow slower. The main thing one has to worry about in a planted tank is balance. If something is out of balance the plants won't grow, or algae will take over.
Hope this helps!!
