Good luck with your meds and future yields. There definately a lot more info on LST plant growth, reading is key. There is a method where you simply apply slight concentrated pressure with your finger tips over your desired spot on your plant- I think if you do it several times through out a a couple days you can do it without hearing that snap and damaging it. Once again good luck and post some more pics

Oh, I don't know if you said what strain of meds your working with- what is it?

Peace.
