I don't think Marine salt is what you want to be adding here. Sure, it
contains elements, but so does weed killer. It doesn't have any substantial
quantity of the elements you want, but it does have plenty you don't. I am
not sure that your ferns are suffering from a lack of elements. Java ferns
are sometimes susceptible to a disease that causes the leaves to die like
this. I don't know if there is any viable treatment in this case. It is
also possible that they are getting too much light; not necessarily too
strong but possibly too long. Java ferns prefer a short photoperiod, not
more than 10 or 12 hours of light. If you do want to add supplemental
elements, try a commercial aquatic plant supplement containing (primarily)
iron. There are many brands out there. See if your LFS carries any. If
not, there are recipes available to make your own.
