Normal for Sour Diesel?

[copperrein]

This is my first time growing this strain. I'm not sure if that leaf curl is normal or if I'm causing stress in my plant. I dropped these on February 26th. FFOF with a little Geo Flora veg and some rapid rooter. Well water with .4 to .7 starting EC not buffered. Aside from the curl she and the others are happy

It doesn't look like it's over-watered to me but I've never seen leaf curl like this.

Thank you!
