Yellow tips, nute burn?

I transplanted my plants (about 1 month old) into super soil 8 days ago, today some of the plants are getting yellow tips.. Not bad really, just dont want it to get worse. Some one know whats wrong?

its a little hot. should be fine. nothing to do but ride it out.

Looks like it. Give it a little bit of tap water. Help it take in the nutes faster. There fore less damage

They look great to me. Just got the "hot feet" that's all. They'll snap out of it and explode with growth.
