So do you think I should do another flush next watering and flush until the ec is closer to 400 or 500? Or should I do that asap on those 4 yellowing out bad?I look for the runoff to be very close to the input ppm.
And I never let my garden show anywhere near 1000 ppm or 2.0 ec. I grow with .8 to 1.4 max.
The lower ppm plants above have nice flat green leaves. The higher ppm plants show more leaf stress.
