Is it unwise to top a nute burned plant?

Hey all,

First time grower here. Im still drenched behind the ears here. I have a few young plants that are nute burned (clawing). Two of my plants are at about the point where I would want to top them. Is it a bad idea to do so given the plant's current status? I dont want to over stress the plant but I also don't want it to grow too tall since it is in a cab. Any help is muchly appreciated.
