NORTHERN LIGHTS AEROPONIC

26-9-2019 Nutrient Block.had to drain and refill so she is on the mend PPM it 1850 not sure why Salt buildup . We will see how she does in the next few days. 28-9-2019 Well I seem to be having the same issue i am having with the White Widow. i believe it was nutrient lock but could be mag or Phosphate deficiency caused by high PH . i changed the Nutrients a few days ago and brought down the PH to 6.20 from 6.3. the nutrient level was close to 1600 PPM she now sits at 760PPM after the drain and fill. i will add some Cal-Mag if she doesn't respond to the refill in the next day or so.
