I had the same exact thing going on, nute deficiency due to pH issues in my soil creating a lockout, my runoff was at 5.9 too, I also used recharge and it did help a little, I ended up jus using pH water to 6.6-6.8, let my soil dry out, next watering I kept watering testing my runoff till it was at 6.2, my plants seem to be bouncing back, hope this helps check my diary on glueberry Og Auto, good luck growing.
