I use Flourish and Flourish Excel, that's it. I seem to break the mold in plants at times. I use no root ferts. My amazon is in the pohot in the link in my sig, on the bottom right hand side. It came to me in bad shape. Now it's a lovely deep green with many leaves.
i'd spend the extra money for some of the substrate tabs meant specifically for the aquarium. i used some jobe's spikes and then one time after a gravel vac one got uprooted and floated all around the tank, and now i have a breakout of algae of which i have identified at least 5 different varieties. i have never seen anything like this despite all my other newbie trial and errors while working on making a planted tank. leave the jobes for houseplants and just get the root tabs if you fertilize substrate at all.
Not many folks no this but Amazon need extra iron in order to really flourish. The symptoms describe seem to fit into the category of not enough iron. I've grown amazon swords in low light with no problem. Try it! You AS might like it. But be careful. Too much iron can cause the worse hair alga bloom you have ever seen. Get an iron test kit if you decide to try it. Needs monitoring.
