2 week in DWC. Auto sour diesel haze and auto Northern light. Which deficiency is this? Potassium or calcium maybe Using GH line.
What about your ph (runoff too)? Before you run into ANY conclusions about deficiency or overabundance of a nute you should ALWAYS check the ph first. PH imbalances can cause all sorts of bs on your plant. And actually those spots could be an indicator of ph imbalance.
