Why are you always jerking eachother off on every thread Lmaoo? its like you have to have someone always certify your ideas, just so people will believe that you know what your talking about. I actually know what im talking about rather than just saying pinch this or cut that, I know what happens when you do that and why it happens. Let me briefly explain for you dumbasses that insist that you know everything about plants, and anyone who disagrees with you is automatically wrong.He reminds me of this auctioneer. Exuberance will get you in deep doo doo!
You ever hear of Abscisic Acid? It is a chemical compound that regulates stem and bud growth and bud and seed dormancy. Abscisic acid is primarily produced in the leaves of the plant inside the chloroplast and it controls hormonal concentration in the apical meristem that alters the last set of leaves in a stem into a leaf covered protection system for the flowers. Even though Abscisic Acid is chemical compound it still functions like a hormone. When it degrades or catobolizes (i think thats how you spell it) it affects the metabolic rates effecting cell growth and the production of other hormones in the plant. When a plant is in its seedling stage, the Abscisic Acid levels are at its highest, then as the plant matures, the Absisic acid levels begin to decline. Once the plant produces offshoots with fully functioning leaves, the Abscisic Acid levels in the plant begin to increase, that slows down growth in more mature areas of the plant.
I think by removing the leaves UB where the Abscisic Acid is produced, you are regulating hormonal concentrations in the plant and can control each stem individually if you want. Or is this too hard for you to understand?
EDIT:
They way you talk about the "redistribution" is not how auxins behave entirely there is more to it than that. By removing the top portion of the apical meristem you are creating a hormonal imbalance in the plant and removing the concentration of Auxin hormones generally located in areas of new growth. The plant responds by producing more Auxin hormones due to the increase cytokin hormones relative to auxin hormones. This lack of Auxin hormones prevents it from acting as a growth inhibitor to the lower branches of the plant. This imbalance is what causes the newly formed stems to grow more rapidly than the branches that have been cut or pinched or topped.Howdy!
Based on quite a few questions about topping I've received here: https://www.rollitup.org/general-marijuana-growing/13820-fimming-topping-101-a-12.html I decided to reproduce a thread on my favorite topping method published at cann.com about 10 years ago.
To get 4 main colas, let your seedling or cutting (clone) grow to about 5-6 nodes and pinch out (cut) the stem just above the 2nd true node. The node where the cotyledons attach doesn't count. The result will be a redistribution of the auxins and other hormones that normally collect in the tissue of the terminal leader's tip. These ho moans will be redistributed to dormant buds that reside in the nodal axis where the leaf petiole attaches to the "trunk", below the cut.
