I have Flourite as a substrate, use a 36 inch FloraSun cubicle bulb and daily dose Flourish and Flourish Excel.
I have Java Fern, something like a Sword Plant that just put out a new leaf (good), and a grass like plant that was doing okay for awhile and now turning yellow and slowly dying. I had put in a bunch of Sera Florenetta A iron and mineral tablets in the the gravel awhile ago.
Why is that one plant dying? I leave the light on overnight when I leave the office.
I do water changes once a week. What is next?
Or what is happening to that one plant?
