Hey guys,
throughout my readings about the optimum ppm needed for each stage the plant i noticed something,
i read that the stage of veg should be around 600-700 ppm.
I‘m planting in soil and i been feeding plane ph water and the in ppm is 80 and the out is 470 ppm.
when they say my ppm should be 600-700 is it the in or out?
because obviously if the in is 600-700 ppm the out would be much higher.
thanks all
In the medium or runoff. Keep in mind that's a general range and some plants can take more and some are fine with less.
