hey man, that's a really nice dwc grow. i'm also on my first dwc grow right now, and i'm using the gh nutrient set. what nutes did you use?
also, i have read to only use about 30% strength nutes. does that mean use 30% of what GH says to do on their nutrient sheet or does GH already take that into account when they tell you how much to add every week?
looking forward to seeing some futureu grows
