I've used Advanced Nutrients 3 part PH perfect for a few months now without issues where on my other tent I'm using General Hydro FloraNova and it has grown WAY slower and the plants don't look nearly as healthy. I'll stick with Advanced Nutrients PH Perfect 3 part and continue not having to PH my RO water and continue harvesting 7 ounces per/plant using LED lights in a 4x8 tent.
There are too many douchebags on this forum that think they know it all when in reality they're just old farts who think their opinion is always right and anyone who says otherwise is stupid or ignorant.
