Nice growth from week 14 to 15. At least looks so, but maybe it’s a blurple illusion.
You may gently push down and out to spread branches, offering some light penetration but mostly for better air flow around the colas. As @DILLIGAF mentioned, that’s important.
Myth buster #1 - buds cannot use light to grow. They do need room to grow and fresh air. Maybe point a gentle fan up thru the under canopy if it’s very thick.
Enjoy your harvest at the arctic circle! That’s awesome!!
