if you are going to use carbonated water to foliar with you should definitely drive a nail into the base of the plant, pick off all the fan leaves, use a really high P/K fert, use no less than 6 additives in addition to your base neuts, make sure there is calming music playing in the grow room and make sure to dance naked and speak softly in your grow room.
seriously though, quit tweaking. They look fine. Check for bugs, calm down. its all going to work out.
