Hey ML, Welcome to 420magazine...Some of your pics are a little blurrier than others so it's kinda hard for me. But I was going to say calcium or mag deficiency when it comes to the browning. Do you have any epsom salt or calmag? As for the yellowing, not sure because if you're in flowering that tends to happen. And at this stage, you should be giving your plant more P and K and less N. Plus you're using Miracle Grow which I don't know much about. Some here use it and some are against using it. So maybe someone will come along who can identify it better than I can. But I am curious about how you're feeding. You said you gave nutes once? Or did I read that wrong? Also, did you check out the plant abuse chart?
