Recently I had the same (apparently) issue. Since I have no exp in such I checked/w
a shop owner who used to be a school biology teacher.
info I received...
Didn't mention name (BBA ?) but he said caused by extra low KH.
Related symptom in my tank's case: extra slow growth of other plants.
Also fine growth (3/16") hair like / green on plant(java fern) leaves.
Solution: #1 get KH test kit...found KH to be very low.
#2 add baking soda...for ten gal tank...1/4 teaspoon...was suggested
it be done once a week and check/w test kit each time till KH correct.
Two doses later (1x1/4 teaspoon each week for two weeks) KH
was at 6.5 level.
Check when water change is made and adjust.
Plants have started growing again and that whatever it is, is gone
and "hair" on java leaves is shrinking.
