I did a res change Day 4 (F25) and tried to continue to spread out the canopy throughout the week. I did a defoliation on Day5 (F26) where I removed 10-15 fan leaves and several extremely tiny bud sites to try and reduce the amount of popcorn buds and promote more growth to the tops. I don't plan to remove any more fan leaves unless they are dead/damaged. The PH has been pretty stable and I don't think I am going to increase the nutrient levels much more for the rest of the grow.
