Hey guys, since I've started using ro water, I've always maintained the same routine on how many grams used for both caso4 and mgso4.
But now something strange is happening.
My water tds has always been 180-200ppm after WC and around 280ppm at wc day.
Now, instead, the water is at 60ppm after wc, and 100ppm at wc day and the plants are starting to suffering again. Pale colors and dissolving leaves.
I remin Ro at wc volume (~150L, 12g mgso4, 15g caso4 - 7:23ppm).
The tds of the wc volume before remin is around 15-20ppm after remin is 60ppm (while before was around 110-120ppm after remin).
Is possible that something happened to my dry salts? I'm almost sure that my tds pen works good because when testing my tap water is says ~400ppm.
