Week 7 going strong. This is the last week of nutrients, this coming Friday the flush begins. The lady on the left showed yellowing on 2 to 3 of the older mature leaves. Hoping to see more growth on her in the next 3 weeks. What are people's thoughts on flushing? Is my 14 day flush sufficient? I also have flawless finish from advanced nutrients. Any thoughts on this magnesium, sulfur finish solution?
