I've never had to deal with a problem like this before, but i'll try to help, alright, did you spray before light out or lights on, if you sprayed when lights came on, or when lights were on, the water may act as a magnifying glass and focus the light in a way that it burns the plant. Also did you spray on top or on the bottom of the leaves or both, I've read that spraying too much on the stoma tends to choke off the plant, I think the stoma is located in the center of the main growth node, not sure, may want to search. hang some sticky traps to catch some the little pests.
