Same with advanced nutrients. If you do pack on the nutes yo definately have to know what you're doing, know your plants, know the signs, know how to regulate, and know how often to monitor and how to keep the perfect balance to ensure they are getting everything they can from what you give them. I think everyone here has seen or experienced nute burn. Once I flushed then followed up with 1/2 concentration nutes and burnt my plants, the ppm wasn't to high the balance wasn't maintained. Plus I'm just sharing what I read. I would be very interested to know how it goes.
