My nitrate was 1.0 yesterday, and i didnt want it to drop to 0 so i dosed, and it seems i dosed a bit too much, and now it seems like im at 8.6 nitrate according to hanna is that a deadly jump?
Unless you are running high par and touchy sps probably not. From what i have noticed there are problems when it hits 0, but adding 8 shouldnt cause any stress. 50, maybe...
