Low Stress training can be difficult to start that far into bud because the stems are usually too thick and strong to bend easily.. You may want to try a bit of LST and HST at the same time.. Tie your plants down as best you can.. if you have multiple large stems you will want to try and pull them away from the middle to allow more light penetration. Just make sure you have some duct tape handy incase you break a stem! Duct tape will save your plant if you tape up the break fast enough.. just a little tip Once you have them tied down as far as you can go without breaking them.. find a space between nodes (If you have some stretched sections of stem.. those are good spots) Pinch fairly hard.. till you feel the the plant matter inside the stem squish a little bit.. then bend the stem at a right angle right where you weakend it.. This often results in damage to the skin of the plant.. so you may want to duct tape the bend afterwords as well... All this does is causes your plants to bush out.. instead of up.. Look up "supercropping" on youtube.. This is essentially HST.. You may need to bend the same branch in multiple places to keep them short enough... But after about 3 weeks in bud they will stop growing up.. and the major bud production starts! Good luck!
