Quick question regarding stunted growth

Sorry if this been covered but I am in a hurry and dont have time to search.

If a plant growing hydro has nutrient burn and the growth been stunted but the roots are still growing very well and look very healthy will the plant recover??

I guess I am asking can/should you visually judge your plant by the leaves or the roots..............thanks for any help

 

Hell yes you can tell everything about the plant by the way it looks
That why you should upload a pic with a brief description of your grow.

 

Yea I know you can tell everything from looking at the plant. When I get home I will post a pic to better describe what I am asking.
