Without knowing your fauna diversity ( % of biomass in swords, % biomass in
stems) its difficult to hazzard a guess.  Swords tend to rely on substrate
nutrition from roots a lot more than stem plants that prefer to extract
nutrients from the water column.  Personally, I suspect the damage caused
to the root mass during removal from the pot and replanting is the source
of your problem. Give the mass time to recover its pre-replanting nutrient
extraction efficiency.

Get some peat moss in a mesh bag, place it your filter. The slow prodction
of peroxides does a number on green water w/o harming higher plants.  I use
a peat moss-vermiculite, sand-Osmocote blend for my substrate at the start.
This prevents the formation of greenwater altogether from the start.

For long term control add 2-3 live freshwater clams to your substrate.
They are great filter feeders of green water.
