Ever since I got the sword (or at least a few days after I got it) the big, tall leaves have been turning see-through brown. However the smaller leaves at the bottom have been fine. I'm thinking the old leaves are adjusting to being underwater? I read that amazon sword is normally a terrestrial plant, and when submerged it sheds it's old leaves and begins to grow new ones. Or am I just not providing enough light and nutrients? I use flourish root tabs, and have a coralife T5 30" fixture, with two 18w T5 bulbs, one is 6500k and the other is a colormax. I was told this may not be enough lighting for the amazon sword though. Should I trim away the dead leaves and see if newer, better looking ones grow? If so, do I cut from the very base of the plant, or just under the leaf? Edit: Oh and it looked fine at the lfs, I don't know how long they had had the plant but when I bought it, it was submerged.
