Will she make it?

Hi yes she look like she make it. I will chop of leafs touching media. Also small steams on bottom of plant. I will add more media so your steam will grow new roots make it stronger. Good luck

You could squeeze the stems a bit, it will heal and get stronger. Would not recommend on Autos because it stresses them.

Hi Der wird mit der Zeit dicker, hast du ein Ventilator an? Die Luft also der Wind macht auch das ein stamm dicker wird. Wenn du den ventilator ein paar Stunden am Tag laufen lässt, aber so saß er nicht direkt auf die Pflanze pustet sonder sie solte nur leicht zittern. So wir sie stabiler und der stam wird dicker und stark.

It will thicken up - according to genetics. Some stress, like wind, can help but it won't have a dramatic effect compared to geentic potential. Your stem is plenty thick for its age. You already have a fairly tight node spacing, so i wouldn't give it any more light (causes shorter, thicker internodes). How many branches do you need originating from the same 6" length of trunk? You'll just end up with an over-crowded canopy on that pace. also, anchor base of any LST so you don't tug on roots or bend through the soil as it resists over time.

It will get thicker in time. also wind. plants bulk up with wind. its like lifting weight for them.

Silica will toughen the cells..Will make the stem wood like if given enough... Hope this helps.

Various types of training and appropriate inputs of light and nutrients, and time. The ol' rub it in-between your fingers to gently break the cell walls is as rough as I'd go with LST. Over time the trunk will be thicker, implying more capacity for water transport and thusly growth.
