These things wont slow down. I've had stretch plenty of times, but these are on their own level.
I've defoled almost every watering to try and get the light down into them and keep the air flow. I also have the light smashing them trying to stop the stretch, but it's just something i'm going to have to deal with.
I will start with the bloom nutrients next watering.
The flowering seems to be coming on very slowly, and I think these will be slow finishers.
Whenever I see them in the afternoon (a few hours before lights out) they are all pointing up like you see in the photos, which almost makes it look like they aren't going to flower. I will have to check them in the morning when i can on the weekend, but I'm sure they are turning.
