Light burn or nute burn?

I noticed it after I started giving her supplemental lighting. So I tied the plant down. What do you think? Nute burn or light burn?

Well is it only on leaves nearest the light, or is it on all the leaves at random?

I have only ever seen one instance of true leaf bleaching from overdoing the lighting. I have seen hundreds of instances where people burn with nutes. I will say that the added light and heat could cause the plant to naturally uptake more nutrients, meaning that a batch of nutrients which may have worked perfectly before, may be too strong now for the environment. Change one part of the plants environment and ecosystem, and there will be additional changes elsewhere.
