You are probably right, that makes sense, it may be best to keep using the RO filter.
But if you are not able to, a gypsum flush would certainly help.

Along with a gypsum flush, I’ve been foliar feeding. Having different dry nutes I “attempt” to tune my foliar what I believe they’ll be hungriest for. I’ve got a gallon of 400ppm Mag powder to use later today. Mbferts for a source.
Even if I’m wrong in what I think plants need, I keep my head in the game more. Notice things sooner.
Lots to learn, besides what I forgot cuz I’m so stoned.
