Melting Java Fern

Over the past 6 months or so I have been doing the EI method on my 190 gallon co2 tank. My java ferns went from puny things to absolute monsters completely covering 5 pieces of mopani driftwood. Then My co2 tank ran out and it was 5 -6 days before I could refill it. My java ferns melted almost like crypts back to almost nothing. My question is could this be due to the co2 levels dropping so rapidly or could it be something else?

P.S. What a mess :(
