Stalk seems weaker than the rest?

I have a few going and out of all of them one has grown twice the size as the others right off the bat. It's always looked better: of course that's the one I nearly destroyed transplanting it last week when about 30-40% of the soil fell off and took the roots with it. Of course I freaked because it's the best plant.

So I got it in its new pot and after about 2-3 days it recovered and is back to growing like crazy and looking amazing even compared to the plant in 2nd place.. However... The stalk is weak, I have pencil laid down so it doesn't fall to the one side, but it's crazy healthy. If I tug just the tiniest bit on the stalk it feels like I could uproot it with no trouble at all, compared to the smaller plants that when i tug the stalk a tiny bit it feels like it's in concrete and not going anywhere. I'm worried this will be a problem in the future when it gets more weight. It's only 2.5 weeks old.

Looks really healthy, im sure it will outgrow the support in a few days.

PS: People here tend to not like those blurple pics, for me its not so much a problem but if you can color correct them or just turn lights off its easier for people to help diagnose problems.

good luck!
