Small stalk on young plant

I have 2 white widow autos that are almost 2 weeks old. One of them is growing much faster than the other and its stalk is weak and will lay down in a breeze or in front of a fan.
I dont think I am overwatering and its beginning to make me worry that the foilage is getting too heavy for the stalk to support.
I plan on transfering to a final pot this weekend and then LSTing it when it has 4 good nodes.
Should I worry about the main stalk being so flimsy?
The plant is nice and green and has received no nutes as of yet.
I purchased the seeds from ILGM by the way
It is just now starting its 3rd node and its about 5 inches tall above dirt.

You might have to support it with a paper clip or something for a few days. Stand it upright, keep the fan going, should beef up pretty soon. Careful about overwatering when they’re small.

Thanks currdog. Im hoping that stalk toughens up. Shit she has no legs!!!

When I transplant should I maybe park her an inch deeper in the new pot?

Ive raised veggies from seeds the same way Im doing these WWAutos and Ive had to support some of them also. I guess at 5 bucks a pop for mj seeds its more worrisome that if it were a plant from a pak of veggies at $1.49 for 50.
Guess maybe Im getting overprotective!!

Cover the long stem with dirt to hold her up.

Move them closer to the light, or increase the intensity of the light. Long stems are seedlings searching out light.
