yes, ro water has diminished quantities of all trace minerals, that's why your tds meter should be reading from 2 to 10 ppm for your ro output.
yes, you need to replace these. i'm just getting into growing, so i'm the wrong one to ask as far which one's and how much, i'm sure someone will jump in and help out. i use ro for my fish tanks and i have to add stuff back, the good thing is that i control what goes back. i'm not going any deeper cause it's two totally different set-ups.
i just use the pre-filters for my plant water, which removes all chlorine/chloramine and most of the sediments and has a tds reading of around 100ppm or so. i'm fairly sure at 100ppm i should be leaving anything my plants need. i will going with BMO's full line for nutes, so that should take care of anything i did lose.
i know this did not answer your questions, but i'm sure someone can...................
