I have issues with my swords as well. leaf by leaf they seem to just start turning yellow, and even transparent. I just ordered Seachem root tabs, and comprehensive plant supplement. I'm hoping this will help. I also mixed sand in with my gravel to add a firmer texture to my substrate. With the CO2 running and lighting (1 54watt T5 HO, and 1 54 watt aquaflora), i'm hoping things turn around....pesky swords.
your thoughts?
