Have you ever seen leaf lite this?????

I have 11 plants at 5 weeks old and found this leaf today...I have just never seen anything like that...exactly half of it is green and healthy and the other is light green/yellow... I dont think its a problem since everything else is ok...other then that one leaf...Do you know what it could be from? Thanks in advance!

check my baby out at 16days veg updating soon with 19day veg pics under 400w mh

Thanks you are probably right...its just strange that its exactly half.
