Unfortunately that won't help with leaf bugs. People use it to prevent or treat fungus gnats. At this point in the game a foliar treatment isn't advised. If nothing else, you're adding moisture within the buds and could risk bud rot. It looks like you're close to finishing. Keep an eye out for any further evidence of leaf damage. If you are within a week or maybe two of the harvest time paper, you can harvest. You may not get quite the quantity you hoped for but your trichomes with be mature enough to get some quality smoke. I was forced to do it before. It beats ending up with nothing after all your hard work. I've seen guys lose entire crops because they decided to gamble and lost big time in the end. The choice is yours.
