Mollies are tough as nails, adding salt is suggested to prevent diseases namely.
I've never seen any issues with them, they can and do move from salt to fresh after all(given enough acclimation).
I'd suggest using marine salt, not NaCl for them.
Their health would improve, marine salt has different ions and more traces the fish are acclimated to. I use marine salt in place of NaCl for table salt for that matter.
Some plants are fine up to 1.005 salinity, not more than that unless they are some species that are pretty salt tolerant.
There are no real salt loving FW plants, they all hate it, they just can deal with it better than other species, but it's a large energy expenditure.
Given that the mollies are pretty tough, I'd just add some GH booster to get about a GH of 3-5, leave it at that.
I've found Sailfin mollies in Florida going from a pH of 4.7 and a KH and Gh of 0, to 1.010 salinity and a pH of 8.2...........
And everywhere in between...........
Seemed fine in each place.
So I'd go with the plants and not fret over the KH/pH.
