At 600-700 ppm, I simply burn them...350ppm is nothing. Over 400ppm shouldn't be too much. I'd be around 6-700 or more.
I use a tote...i agree with @growsince79 you should be way higher then 350ppm. i used to stay around 900ppm bu this round im at 1.8ec and plants are taking it.
what and how are you mixing your nutrition?
I don't do co2, but maybe that's the problem. I can't imagine why a plant that can't handle much light or nutes would need extra co2.At 600-700 ppm, I simply burn them...
My maximum achieved over few runs was 460 ppm and I was overdosing a lot!
the 460 ppm was nutrients, not co2..I don't do co2, but maybe that's the problem. I can't imagine why a plant that can't handle much light or nutes would need extra co2.
