If you sprayed during lights on youll get leaf burn. To me it looks like, nutrient burn with light burn but also curled tips are a sign of ridiculously high PH. if you're using water or a made spray it still needs to PH corrected. I suggest you use some Calmag if you haven't because it definitely looks like you're seeing a calmag issue as well.
