Limp seedling

Hi all, just a tiny problem.
I have four ak47s that have been planted in jiffy pellets. All four have taken but one is limp and bent right over. The question is do I just leave it and let it right itself, i.e let its stem get bigger and stronger itself or do I help it with a stick to prop it up. Or do I run the risk of the bottom part of the stem never recovering as it has had help with the stick?

If it's not damped off.

Use a toothpick to hold it up.

Then, plant all of them deep. Just about right to the starter leaves (cotyledons). You'll get better rooting out of that stem under the soil.

I forgot to say they will be grown hydroponically in clay pebbles. Many thanks for the advice

Will the stem repair itself and get stronger over time? Never had this problem before

Yes.
Unless it doesnt and it just dies.
