Leaves curling up?

[Gallant Reflex]

My sprouts are 15 days old, grown in soil, no nutes just water. On one of my five plants the leaves are starting to curl up around the edges. What could cause this? Thx

if both plants are doing it your are probably either over or under watering the plants.. how often do you water? what is the pH of your soil/water?

The pictures are of the same plant....only one of the five are curling. I water every 2-3 days. I do not yet have the ability to test PH.

the most likely cause is heat stress from a light to close, second is magnesium deficiency.
