Just fed my girls two days ago and the run off was between 1300-1500 ppm. I was going to do 100% distilled water for their next watering but some of the leaves are showing nutrient deficiencies (calcium)...should I just do 100% distilled water to lower the ppms or should I add CalMag to the water for the next feeding?
FYI I am in week 4 of flowering.
Pics would help also what’s your runoff ph
I’ll take pics tonight. pH is 5.9
