I know this was posted a while ago but, it looks like Phosphorus deficiency, maybe some nutrient burn based on Grow Weed Easy's symtom library. What pH are you watering at? Also your PPM going in vs PPM runoff? Also do you have any updated pictures? Unfortunately, your leaves will lever turn back but your flowers should be ok since your fan leaves are your first line of defense against toxicities and deficiencies.
