Leaf burnt edges

i can see signs for different deficiencies i can't tell you exactly just from that one picture. what i can give you is some advice to help your plant recover: -do you gave the right pH? do u have a pH meter? no? thats bad. destilled water got an "ok" pH for plants in soil but then u have no nutrients in the water but thats better than a fucked up pH. -u gave them fertilizer already? give them 1/4 the amount of nutrients and SLOWLY increase to 50 or 80% during flower. feed nutrients every second watering should be fine. -don't overwater your plants that can cause a nutrient lockout. there are plenty youtube videos on how to water cannabis correctly -don't send them into flower, if they have deficiencies. you should start documenting your grow here as it's easier to help. you can look at my recent growdairy where i fixed a problem i caused with pH water to 5.5 (thats good for hydro) instead of 6.5(which is good for soil) and had to veg 2 weeks longer just to fix that. Good luck growing!
