Nute burn (pic) fed to early

Plants are only a few weeks in they where looking great decided to feed I fed way to early considering I'm using ffof I fed yesterday should I flush right away or wait till dries out a bit any help greatly appreciated won't let me post a pic positive it's nute burn tho

You learned a lesson we have all learned...
Nutes need to be watered down...IMO, Room/Soil temp should also be same temp as water....in the beggining...
As your plant gets older, they become more hardy...Treat um like babies...
Good luck...
