1 grasshopper? I've had em so bad that when I shook the plant, hundreds flew off like a grasshopper bomb. The leaves looked like they where shot with 12 gauge bird shot. The plant outgrew them wonderfully. I got a canister of semaspore for grasshopper warfare but there aren't any this year, must be an off year. They usually attack the fans and not new growth so don't bring in the hazardous chems. Your plant will be more potent after a bug attack, thc is a natural defence against pests.
