I got a question about pre harvest flushing im growing in soil and i read somwhere that when your runoff is bellow 400 ppm your plants are flushed i started flushing 4 days ago. First flush was 4 gallons through 5 galons soil with about 3.75 gallons runoff at 1560ppm . I have been doing this every night and i have my ppm down to 460 in runoff . Will this method work or am i just reading the crap in the soil? Any input much apreciated.
