Week 5 flower.I had nute lockout .I think, I checked my runoff last week , it was at 2200ppm , So I just gave it water, checked today 4 days later. Runoff is at 1400 ppm. Should I give it water, or a feed of 800 ppm?
1400 is still quite hot. Unless it's a tree, I would keep it under 1000. Feed just water or half strength. Whatever is getting you to the 800-1000ppm mark.
