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.

Go hard on some LST!

If they're photoperiods and you haven't switched to 12/12 yet just top them to even things out. Topping doesn't "negatively impact yield" if done before flower starts, lol. If topped and trained properly you'll almost always INCREASE yield as more of the plant grows in the best zone of your light vs allowing the plant grow like a tree. You want to fill out your light's footprint. If it's and auto, it's too late to top now as it should transition anytime now. You'll have to get by with aggressive training. I don't think I would supercrop at this stage, save that for evening things out mid flower.

Hi bro, At first, I'd recommend starting with extra base for the smallest plants, gradually increasing the level as all plants grow similarly. One day they will cease growing and begin to put all their energy into the buds. Do not top them as it will negatively impact the final yield. Best of luck, buddy.

The tallest one looks like it has a great start if they have started flowering I would not top them that will mess up your yeild big

If you are still in veg, I would cut it down a few nodes and then bend it over and tie it down to a tent pole or something. The topping will slow vertical growth and start sending energy to lower branches, the fact the plant is now bent over and tied down, the middle/lower parts of the plant are now exposed to more light offering more growth. Increasing light intensity can also slow vertical growth, if you ever see plants stretching and they're not going into flower, this can be an indication there's not enough light and the plant is reaching for more.

Next run I would top them early, you have room in your tent that is going to waste :) more vertical grow would be good for yield and also bud quality. I would guess 200% more yield(300%total), the quality increase is hard to measure or guess, but ur buds will be more on one height and therefor more potent

wait till they stop growing and suppercrop it, before i wouldnt do it. In the meantime i would use sockets for the smaller plants to get them on a similiar height, so the difference doesnt get bigger due to Light for now

"gently" snap the cola at the top. First 24h you may need to support it, but after that you'll want to hold it down so it doesn't immediatly curve back upward. Snap below the height you want, because anything beyond what is held down will curve upward from there. some parts of the stem might be too rigid to do this, so this will impact where you snap it too. Can roll it between thumb/finger to weaken a point if there is a concern about snapping the stem. The goal is to do this with minimal vascular tissue damage -- when the leaves don't wilt initially you've mastered it well enough. If leaves wilt in first 24h, you're doing a bit too much damage to accomplish the task. stems get rigid over time. if too rigid this is very difficult to do without completely severing or nearly severing the branch beyond self-repair.
