It's no laughing matter, you're right to experiment!
A few tips for the future:
Here, you haven't really done a topping, but rather a fiming (https://2fast4buds.com/fr-en/news/all-about-fimming-autoflowering-cannabis-plants); why not, but the LST that follows will be different.
You started a little too early; you have to wait until you have five nodes, and then cut the last one. After that, it's up to you whether you keep the branches from all four nodes or just two to make a cross (that's my favorite method).
Remember to fill your pots more, as your plant's main root will dive into the soil until it hits the bottom before growing sideways, and it's the length of this root that determines the size of your future plant.
Finally, I get the impression that you're watering a little too much, without providing all the necessary nutrients (we can see little spots on your leaves).
Keep going & enjoy! 😉
