m0useanswered grow question 3 years ago You still have time, they are looking to be the prefect size to do some LST, go slow and don't rush it, nobody wants a snapped stem.
if you use the explore function on the diary page you can browse others using LST on hydro grows. Can use them as reference points.
Only do what your comfortable with. This is your grow after all.
Best Of Luck!
