Do not untie,is looking great,now she is going to strech,keep training if she want to go back in some wrong position.but def you have to reduce the amount of training during flowering.
Good luck 👊🏽🍀
Nice looking plant
I leave the LST strings/ties in place till harvest.
Sometimes I move them around the branch to help get better light and air movement.
If left untied the plant may start to slowly go back into its old spot depending how new/old the growth is.
Happy Growing!
