I just had to s/crop two bout 5wks in.. Just chopped them this am.. looked just lovely no probs at all.. Thats not to say you wont have a problem.. All depends on the genetics of the plant.
Why are you trying to super crop? it will stunt that branch for up to two weeks depending on a few variables, do you want to chance it? I dont see any benefit without giving it veg time to heal and create a fat knuckle. If your trying to reduce height, bending the branch over puts much less stress on the branch, and will keep it short.
yup...soma said adam from thseeds does it up to three weeks in..and i've personally done it about two weeks in..you'll be fine just make sure you do it lightly no big juicey tear u know..lol
