it sounds like your substrate fertilizer is over... what did you use - if
any - when you first set up the tank?

I disagree. Crypts are plants that _prefer_ different form of nitrogen
other than nitrates. It seems that they are less able to reduce nitrate
than many other species (that could also explain why they loose leaves
sometimes), and beside that they have a very well developed root systems,
so I would go for a _light_ fertilization of the substrate, with some
tablets that contains nitrogen _also_ in NH3/NH4 form.

I would try to get a _much_ ofter water for sure !!!! I would go for a KH3
at least!! And same TH because you _need_ some calcium and magnesium.
