Java ferns not lookin good... HELP

I have a low light (1.5wpg) planted discus tank,kept at 85f.(NO CO2)

Before it was a discus tank,the same plants where kept at 76f as a community tropical tank.

Since the discus set up im now Useing 100% ro water,which then i add RO right too,to get my GH back up to 2gh.
Then i add ph stable to raise my KH

Now my problem java ferns arnt doing very well (see pic)...thay are going brown and holes are appearing in them.

Could this be a nutrient deficiency ??

The RO right contains traces and twice a week i add flourish.

MY n03 is 10ppm p04 is 1ppm

should i BE ADDING k?..but bearing in mind this is a low light tank.

OR.....could this be due to the rise in temp from what thay have been kept in 76f to 85f?

also is it safe to add K to a discus set up?

My guess the temp is too high. I have a hard time with this plant in the summer.

I'm willing to bet it is a Magnesium deficiency. I had this same problem a year ago with my Java Ferns. Your pictures look almost exatly like mine. After about a year of good growth, they started looking like this. I had two huge java ferns, but over the course of a number of months, while I was trying any remedy I could think of, they almost completely rotted away. Finally, I started adding about 1/4 to 1/2 tsp epsom salt (magnesium sulfate) with each water change. Shortly there after the java ferns starting growing well again, without any rotting. They have been doing fine since.

I think magnesium is a micronutrient that they typically have a decent amount in storage. However, after a long time of mag deficient water, they finallly used up their stores.
