Looks like there's too much N there with the deep green clawed tip not sure how that develops in late stage though but looking at Google images for a cannabis deficiency chart one suggest a manganese deficiency but lol I'm not sure to be honest.

A flush with PHd water should correct any PH issues and fix any lockouts.

First thing I'd check is pH. Have you been pHing your feedings and waterings? What are you growing them in? Have you checked your pH and ec of your runoff? What type of nutes have you been using at what strength?
 
yes i have i checked the ph run off and its fine but my ppm was like 700 when i was using 0 ppm water.

Soil is the medium and using advanced nutrients line feeding usually around 800 ppm
