Hrocks,
I tried to find anything causing that brown residue and figured it was minor mineral build up since the roots look great.
tds meter is fine. I tested/calibrated it. (too many times this week)
Just finished reading a lifetime of r.o, and r.o de-i info. R.O is fine as long as you add cal mag and the minerals removed. HOWEVER, "De-i" is cation exchange and positive charges the molecules to bind cal, mag, iron, etc.. and exchanges them for salts!
I read an article saying its no good for hydro because h2o is positively charged and forces minerals in nutes to fall out of solution in reservoirs.
Any one else know if this is true? Could be my problem?!
