Weird yellow pattern on my seedling

Anybody recognize what might be going on here?
350ppfd
1000ppm co2
80° f
70% RH
Hydro 6.2 PH
0.2 EC (150 ppm)
Day 7 from sprout
50ml top feed once a day untill roots are established

Might just be because she's a baby....the cotyledons aren't yellowing yet so she does have some nutrients. Might be best to just leave her be for a bit and see how she grows.

I got three more, one has a little yellow similar, while the last two are a healthy green.
This one with the most yellow is the biggest though lol

Ive ran several rdwc grows and have never hand watered.If you keep the leca wet the roots dont need to search for moisture.My theory anyway.
