Have you used PK 13/14? Maybe a bit too much? In what medium are you growing?
What i see: it's IMAO a P and K overfertilization.

yeah...they are growing under 600w light. and in compu soil.I use only bat guano as a fertiliser...

I flushed them 3 times  and I hope now they will recover a little bit

Don'r worry! They would! Bat guano is very high in P. 

Can you messsure the PH of the drain?

But flushing should done it, because there is no much time left...
