Autoflowering 2 week old plant trouble

This is my first grow and I am using lowryder #2 auto flowering seeds. I have been growing them for about two weeks now and am noticing a yellowish color on the leafs. I have read this is probably because the pH is off.
If that hypothesis is correct then can someone tell me how I need to go about fixing the problem.
Any help is appreciated.

Check out the pictures

Thanks

Looks like nute burn. What soil and nutrients do you use? Otherwise they look good.

yup....looks like over nutes ^

I have not added any nutes yet. Just have used fox farms soil
