Malformed 1st leaves happen, see my Dwarfen Lady diary. She had a strange growth pattern at first, but pulled through and developed to be the biggest girl in the box. So nothing to worry about ... yet.
The stretching of the other one is a different matter. Looks like she is getting not enough light to me.
I would lower the grow light by at least 30-40 cm. I tried to have a distance of 40-50 cm between light and plants, and that worked for me
