Yes I am guessing that you sprayed when the light was to intense but your plants look gorgeous and are at the point where the hairs will go orange anyway....

If you spray on your plants, the time to do this is when the light is off. So it have time to dry and so you. don't have any burn sprouts Good luck

If your saying you sprayed a super light dilution and then the next day she was browned the pistols then I would say it was the doctor zyme spray ... It's supposed to be good for all stages and everything I understand that much ... Did you spray in morning of your light cycle as is best time right as lights come on.. sometimes it's best to try a small patch of the grow before spraying the whole plant .. she gonna produce more pistols and all so should be fine ...
