DonCostrostarted grow question 1y ago

Hello, should I keep adding cal mag supplement during last weeks flushing, if my water has very low 70ppm? Adding it in the amount I normally use puts it at abt 150ppm (0.26mS). Growing in soil btw.

I wouldn't bother, just pH your water. If you're in your last week you won't have time to develop a CalMag issue suddenly. Save your nutes.
