I'm not sure what is lacking in the plants diet, but all of my leaves are turning brown, and then going see through, then of course falling off. My Anubius barteri, isn't doing so good, my Amazon Sword isn't either. My Rotala rotundifolia is dying. I just added some new plants, Lysimachia nummularia, and Ceratopteris thalictroide, which are okay so far, and my Anubius Nana is doing better then the others, The small amount of Tiger Lotus hasn't grown much, and doesn't look great, and my what looks to be Java Fern hasn't grown any either. Phew! Am I correct on the names though? 
Anyways, I dose C02 (sugar yeast) and all of the plants are in flourite, and most of them are in these plant pots with this fiber type stuff covering their roots. I have started adding some Flourish comprehensive supplement, but it didn't help much before. What should I be using? Is this like a Iron deficiency?
I've spent over 100 dollars on plants, and I can afford for them to die
Help me!!
