Not a fan of "flushing" in the typical sense, I prefer weaning nutrient concentrations down And have been much happier with my product. First week of running with just a trace of Grow nutes, should start seeing some fade soon, didn't start early enough on the last auto - I'm on it this go around. Keeping CO2 and ppms stable for a few more weeks.
@Autogato_organic, this is only my 2nd Auto run so I'm not sure if I had the lighting intensity correct so they stretched more. But I've been very impressed so far - hope all goes well for your run of them!
