Dwc Calmag Agent

TheVomitstarted grow question 2d ago

Hello. My question is for experienced DWC growers: how much Cal-Mag Agent should be added to the water? The water is 0.3 mS without any nutrients.Now, for a 7-liter nutrient solution mix, I added 0.5 ml/L and I plan to give it once a week. Vpd is around 1.2. Thanks.

Depending on the growth stage: Veg, you want to target 160ppm Ca, 24ppm Mg. In flower 140ppm Ca, 14ppm Mg. The amount you use (ml/L) depends on the strength of your calmag product.

The amount of Cal-Mag a plant needs depends significantly on its growth rate. Follow half dose recommendations and work up.
