General hardness isn't really the problem and that level should be fine with most plants. GH is actually a good thing. It's KH or alkalinity that causes the problem and shouldn't be too high.

A lot of the plants I kept suddenly started dying off with no changes in the tank or dosing regimes, in particular the Blyxa which died off and the L. Aromatica now grows very slowly in comparisson, could the parameters in my water have changed? Since I never measured them before.

Could well be. I find Thames Water's water parameters change quite a bit during the year, hence why I don't use it. Blyxa has a habit of melting if water parameters change, but grows back fine again.

Mine melted completly until there was nothing left :( I miss my Blyxa!!! hehe I have to keep a track of the parameters and see the changes, maybe test them once a month and report back.
