Yeah, I have those resources save on my favorites, and looked at them before posting. It's honestly hard to tell if it's nute burn, or magnesium. They look fine, new growth looks nice... have my PPM at 860 right now. I have about four weeks to go, so I'm going to give them a high Phos. blooming nute (Shooting Powder it's called) for a few weeks, then do a ten day flush at the end. Will post some pictures.
