The only thing could be "over-feeding": too strong and too many x's per week. A plant really need to be feed 2-3 x's per week - but being an auto you are in middle flower so consider a short "flush" (4 days) with a dry day or so after flush, then start using corrected amounts of nutrients . Use root juice till week 8 of flower. you plant has only at most 2 more month's till harvest

I did everytime i do that its , i saw a chart for the lights and u can put it till 20cm distance for 250 w hps. and if its light i need to bend?
 
Went back and looked at pics again...I see no nute burn signs really....our curled top leaves on tops...you might just have a ph issue....but I did see you are using both grow and bloom nutes at same time...nooo she is an auto and in flower stage so feed her bloom nutes. Might also be a nitrogen toxicity due to that...

Ph make even 6... Always
6.5 is not enough fudge room
 
i just followed the program of biobizz didnt know about grow, and i read that bio bizz soil need nitro for flower just a bit , is that true?
 
Autos only require a fraction of the nutrients usually given to cannabis plants.
no more than 1/2 what you would normally use .
 
oh really didnt know wthat i thought u should give them the normal bio bizz schedule since it short in time and u mest get the most yield out of it
