Hey lowded,
Hope the battle against the bugs don't cause any hermies for ya. I would first find sacs on the lower popcorn stuff, and the younger shoots. it then seemed to progress up the shoot, but I don't know where you were spraying for bugs if they would appear at the same locations. I think rooster had some hermies appear from spraying for bugs, he should be able to point you where to look.
