I am showing signs of nute burn I have scaled back my nutrient from 900ppm to 750ppm is this enough or should I flush @ 000ppm and for how long?
lol... u dont have to flush with 0ppm, just scale down 100ppm and "flush" out the high ppm, till the run off is equal to ur new ppm that u are watering with. and if burn persist then lower again
