Wonderful information funken. Thank you so much.
So I have glued my ferns to my driftwood. But it was a few months ago and roots were growing good. But suddenly this started happening. I made sure to not get glue on the rysome of the plant and used some of the grown roots.
I didn't know that Java ferns did better in low light situations. My lights are on roughly 7 1/2 hours a day. With injected co2. I might need to move them to different locations? Maybe under my swords.
No other plants are showing any signs like this. I am having different signs of deficiency but I know what it is.
Only recent things done to tank is water changes and trying to deal with brown algae that is everywhere. No chemicals added other than prime and fertilizers
