Stickanswered grow question 7 years ago In my opinion it's too soon ! Your plant is not strong enough to handle this kind of bending, it will take several days to "recover" and develop new stems. I've experienced this with a previous grow, I tried to LST an autoflowering strain with the same method at the same time (week3), the result was a disaster : small plant with small bushy branches, it developed some
rottenness and the final weight was disappointing. You should wait for week 4 or even week 5 to start this type of bending/LST. Moreover, you put the string at the wrong position : it should be between two nodes, not under the first node. I'll be around, good luck with this baby!
