Stretching is slowing down, and proper bud formation has started. I've somewhat lost the battle there, not the most even canopy but that'll do. Mid week, I did a heavier defoliation and pruning session, cleaned the lowest part of the plant and removed lots of leaves to get better air flow and exposure to the light. In three days, it looks like nothing was done, it's all bushy again. I'll be cleaning the under canopy, removing leaves and few more branches until I'm happy how it looks.
I got the dehumidifier and now RH stays in range, especially during the nights. Did a full res change because the plant was looking a little unhappy. New solution was maybe a bit too strong, slight tip burn can be seen. Other than that, plant seems to love it and looks very healthy.
