you can start when the plant has a min of 3 nodes 😀 (google "autoflower lst" check the pics for examples) also browse the diary's here, you can select LST in the menu's ..
I like to wait 25 to 30 days so you have some meat, well length to work with.. don't worry those plants are very bendy until flower period.. have fun ..
приветствую, бро! 👋 lst тренировки можно начинать хоть с первой недели жизни растения, но лично я предпочитаю со второй или третьей недели и вплоть до третьей недели цветения, пока идет у растения активный вертикальный рост! 👌😇👍 Удачи, бро!
I would say early as possible I waited to like day 23 wish I did it abit earlya day day 17 but my plants have been growing well from my understanding of your plants are healthy and growing good lst as soon as you feel confident too
