thinking what 2 do with the tall on..? top? lst? n...

Top once, bend apex over tying it to near the ground, lower than side stems and break the main apical dominance, once you hold the main stem lower than the side shoots the plant will by itself redistribute energy to the stem/s closest to a high light intensity (chances of survival), if you create even PPFD during the weeklong recovery every stem will grow as the main. apical dominance refers to the tendency of the main central stem (primary apical bud) of a plant or tree to dominate over the lateral branches. This dominance is maintained by plant hormones, particularly auxins that are synthesized at the growing tips. By inhibiting lateral (side) branching, auxins help the plant direct energy and resources to focus on upward growth. Inevitably, this results in a tall plant with a single dominant cola. However, when you top the plant or remove the growing tip, you disrupt the apical dominance, the production of auxins decreases and the side branches start growing more as well, leading to a higher number of main colas instead of just one. Note that the success of the topping technique depends on the hormonal response of the plant. Topping a marijuana plant causes numerous hormonal changes, including: Fewer Auxins: As you know already, auxins naturally inhibit the growth of lateral branches while promoting vertical growth. When you cut off the tip of the plant, the production of auxins reduces while the capacity to transport it increases, which means the other shoots now get a good resource to grow into huge colas. In other words, they develop with more vigor as they are no longer dominated by the plant top. Buildup of Cytokinins: These hormones are essential for encouraging division and growth in the lower portions of the plant. After you top the plant, a reduction in auxins also leads to an increase in cytokinins, so there's a stimulation of new shoots and branches. In short, the plant grows horizontally rather than vertically, promoting a very bushy pattern. Increase in Gibberellins: Gibberellins are also plant hormones that influence your cannabis plant's development and stem elongation. When you top your plant, these hormones are redistributed which ultimately helps the plant spread more and also helps the plant recover from stress quickly. As you can understand by now, the plant goes through various hormonal changes when you cut off the tip or top it. In essence, topping is a training technique that depends on the plant's natural mechanisms to halt vertical growth and force it to grow more horizontally. Growers can then create optimal structures for light exposure, air circulation, and bud size.
