15 days into first grow. Asking for help identifying problems if any.

I am not sure what I should be expecting. I am using seedsman zkittlez auto flower feminized seeds Grown in coco coir Perlite 70/30. If anyone sees any signs of problems I would appreciate it. Two of the plants I have struggled because when I watered in the beginning the sprouts would move in the soil. They seem not as strong as the other one. Any tips on strengthening them would be helpful. Thank you
