What was your runoff ph? If your ppm in is lower then your out the plant isn’t using the nutrients.
@AutosOnly thanks. The ph in was 6.8 and out is 6.3.
This deep into flower you want 6.8 to 6.5 out for nutrient uptake. Your PPM will fluctuate like that in soil.
Alrighty, I’ll make the change to the ph and monitor.
Thanks
