Hi guys,

my echinodorus bleheri's seems to be doing something strange lately, their
leaves are turning brown, and are getting holes, this is even happening to
the baby plants I got from the main one in my 20G tank which got moved to
the 27G, any Idea?

I don't use fertilisers, and the tanks have been up for almost a year,
although I did change apartments 2 times in the last 2 months.
