I am trying to determine whether or not it is to early to start lst training. Feedback will be appreciated. Plant has 3 leaf nodes with 4th one emerging.
Read up about Auxins (some important info if you are going to be LST'ing). When to start training kind of depends on what you are trying to accomplish.
There are different LST techniques that people use for different reasons. There is no harm in training early. Some people train right from the time the seed pops out of the soil.
