most of what ive read attributes plant melt to fertilization/over-fertilization. particularly when using a product called "flourish excel" but im sure you could get the same results with certain detrimental amounts of most fertilization. ive also read that most potting soils and some pre-fertilized topsoils contain huge amounts of nitrogen because thats what outdoor/house plants like. with houseplants, yellowing/oranging of the leaves can usually be attributed to too much nitrogen.
given the aforementioned, im going to guess (i repeat, guess) that your problem is due to the potting soil you used. but..."dont panic" is going to be your best advice. read up on it and nitrogen in your plants. there are no problems, only challenges.
as i said before, mine is just a guess. i use unfertilized topsoil capped with aquarium gravel, natural sunlight, no CO2, no waterflow whatsoever, and i have 20-something different species of aquatic/bog/house plants growing and reproducing in my 75gal. by most people's standards, my aquarium cant even exist, so you might want to get some other opinions before overhauling your soil. keep us updated. im subscribing.
