Clawing fan leaves with brown edges

Id be checking the run off for PPM/E.C and see what thats like, that kinda looks like nute burn to me. If it happened a few days after the dry amendments then its likely when you watered it in, you then burnt the roots and the plant went into shock. Check ya run off and if its high thats your answer. And dont add any more dry stuff for a few days to a week at least, and next time add less of it too. A lil bit every week is better than a big handful once or twice unless you can see nute defic probs.
