AsNoriuanswered grow question 4 years ago Damn. Do not touch girl in first two weeks of flower !!!!
You should prepare her earlier, but ..
Wait till bud sites are formed, its usually a window from day 15 to 21. For starting grower i would go on 18-20 day of flower.
Don't water girl till work is finished, less breakings.
Don't feed her, just plain water, less stress
Leave at least one nod of fully formed leaves counting from top. If you have one formed and 4 more forming, still leave that fully formed leave set. Normally you trim all leaves from about 3-4 nod.
Check my 8 sisters diary. Week 3 and 6 of flower. 2 heavy waves with explanations.
When you will be working with girls dont even breath on flower sites ;))) really, you have to touch girl without touching.
All the best for You !
