Any thoughts on this one?

Here's the short-form of the setup:
Germination: wet paper towel in a baggie in a warm place
Soil: Coco Coir & Perlite mix
Lighting: 6400K T5

After sprouting, seeds were placed in Solo cups with Coco/Perlite mix.
Then watered with water only (pH = 7.0 or real close)

Plant grows to maybe a little over 1" and then just falls over.

Plant #2 does the same a day or two later.

Must be the soil, right? Any ideas? Had two do this out of my last batch of 5, but also got two plants that did very well.
