Yeah, my first run the stretch on my two keeper phenos wasn’t too bad… the other phenos had a cpl of big stretchers.
Last run I was super pedantic about my LED PAR levels. This time I slept on the light intensity and I think it caused them to stretch for the light during early flower, sparse internodal spacing this run. Maybe try keeping your PAR at the top end during stretch to keep them shorter because yeah they’ve stretched a lot this time
