Hi, I've noticed that all of my grows, the leaves start changing color around the 7 or 8 weeks. I use ocean forest and fertilizer and cal-mag. But they still do this. Is this a normal growing thing? If not, how do I fix this.
The plant is killing off the main fan leaves to supply the lower bud sites with more light. This is completely normal in a plants growth. She old and getting close to end of life, she wants to reproduce so she is trying to make sure all bud sites ripen with the seeds of her offspring. Sadly she didn't get pollinated so no seeds, but that's replaced with bud weight.
