You can pull and tie down quite a lot, but maybe you might get some of those bending training clips I've seen. I don't think they stress the plant much at all.
Now that main stem might just need some rolling between your fingers and bend her down.
Kinda hard with her not in front of me, but If I had her, I'd either pull down or clip train the lowers first and then see where it would be best to move the main.
At least ya don't have to worry about defol with her! LOL!
She's growing like that damn one Linda seeds GG#4 that was totally different from her sister that caught me by surprise with the extent of her stretch and structure. I just had to let her run. I had to make stands to raise up the other two girls in the tent! LOL!
