Could be an over-fert problem. The high level of nutrients accumulates in the leaves and causes them to dry out and burn up as shown here. You must flush with clear, clean water immediately to allow the roots to recover, and prevent further damage. The find the cause of the high nutrient levels.Are you using nutes yet?

More information needed! What nutes, how old is the plant, is it old growth or new growth? Looks like possibly phosphorus deficiency

Yes more info , have you been feeding nutes , if so what nutes and how often are you feeding them , what are you growing in , how often are you watering , how old are these plants , what are your temps ? People here will help you bro . Mine had kind of looked like that and I got some cal-mag plus - fed them 1 time and they came right back . But I dont know if that's the problem here . Are they in soil ? if so do you let it dry out enough between watering .
