You can use hst if you want to slow vertical growth in veg. You can check my diary. “No topping” where I use HST and LST. Just don’t do it in flower and give her at least a few weeks to recover fully.
Just pick a point you want to bend. Massage it by squeezing or lightly twisting( she will start to feel loose. Then just bend her over and make sure to tie her down or else she will try to straighten her self out again.
Most people don’t recommend HST but until you try things you’ll never know:) branches get stronger which is a huge benefit in flower! Good luck!
