My first grow (journal in sig). Wondering when I should start to use Low Stress Training on this plant.
My opinion, wait and top it when it's ready. then when it starts growing new tops and branches do a 4 way LST. Read LBH's 4-way LST guide.
You might also want to burry as much of that stem as possible. Transplant if you have to. It looks to me like you could start training, but you could wait for one more node if you wanted.
i bent mine over and topped it just after it had its 5th node. instead of a four-way LST ive got a two-way going strong.
