He was at 400 ish. Plants looked no better. Then the yellowing which pretty much says needs Mg.Ive done this hydro thing for a number of years also. My clones get feed 300 until roots come out of net pots. Then it’s game on 7-900 ppm. I’ve tried many different strains and only one so far didn’t like above 700. So this is why I suggest at least 200 ppm more then what he had. Plant will tell him soon enough. Also it’s not like dirt where we can’t take away. A simple flush and back to sq one.You can't pH Ro without putting something in the solution to read.
If you put it in plain ro for 48hrs.... Let it purge.
Start it back at 400ppm, CHECK THE #'s. Moving the right direction.... Up the PPM's by 50. REPEAT. Slowly bring her back to a PPM that she likes.
