No, they are not turning towards sunlight as the room is otherwise dark. The two youngest of them are growing straight and true. They have yet to shed the husk but are twice as tall as the ones with baby leaves extended.

I put them in my veg room this morning and now the leaf on one is turning yellow. Same seeds; same soil; same everything except the ones that are tinier and bent over sprouted first. They have good ventilation.

The taller, healthier stalks are purplish green; the ones that are struggling appear to have a more purplish stalk.

The soil is dry as I live in the desert, but have refrained from watering them for a while. Humidity is about 15-18%.

I fear I may lose my first babies.
