Is this plant ready for some LST? I don’t want t...

No, it is too young/small, LST at this stage will just freak it out. Wait until there are 8-10 leaves or so.

You want to wait until you hit the 3-5 node. The objective when you do is to bring the top of the plant down so the growth between the leaves and main stem get enough light and start gaining apical dominance. So you will need to get a plant white between the top growth and the node below it. This plant is so young that node is to small to even get a plant wire between it

WAY too early - poor thing needs a chance to strengthen up!! I honestly don't even start to do any LST until a) the plant has 5-fingered leaves and b) it's got at LEAST 4-5 nodes on them. You've got plenty of time to worry about height issues ... you may not have ANY worries there - and you may have worries all the way up to harvest... but you won't know that until you give her a chance to grow... Relax, be patient, let her get her strength! Good luck!

I agree it’s way too early it’s literally got it’s first true leaves. I’d wait another week or two

It's definitely to early for LST give her another couple of weeks to grow a few more nodes

Ja, ich würde mich damn_dorothea anschließen. Für LST ist es noch viel zu früh. Am einfachsten verhinderst du das sie sich weiter streckt, indem du die Lichtquelle näher an die Pflanze bringst. Oder eine stärkere Lichtquelle wählst. Und auf jeden Fall den Ventilator nicht vergessen. Durch den Luftstrom wird der Stamm stärker und dicker, die Pflanze somit widerstandsfähiger. Weiterhin viel Erfolg! Gruß
