DWC - Critical Autoflower

Bio heaven is never enough, it is a additive that doesn't contain everythings the plants needs to thrive. You can find the hydro chart of every nutrients brands with Google and generally the hydro chart is the same for DWC ( sometimes the brand can make a different schedule if you are using a recirculating system or a system like yours ). You can grow hydro with Bio bizz BUT they are better in soil or coco , in hydro I prefer to go with mineral feeding to avoid bad smells
