If your plants are still bendable at the top, try
bending the tops over(slowly),as low down the branch as possible
without breaking and point them right towards the soil, then tie the top to the stem.
This will lower the height and give a lot of light to a few more bud sites, I've had to do this
a few times because of height issues, it will also harden the stalk and slow the stretch down lots.
Hope this helps๐๐
