I look for 6.4-6.8 in
@mwhite9829 I watered at 6.4 and runoff was 4.7. Does that mean nutrient lockout?
Have you been watering low h for a while? If my medium gets low like that I usually flush fairly heavy @ 7.0, then finish with 1/2 dose nutrients at 6.5. next watering I'll check run off again.
@mwhite9829 dont want to sound stupid but I have never flushed my plants. What is the proper way to flush?
If your using 3 gal pot do 6 gals of ph correct water is what I’ve always heard
