Please help, I have an infestation of something and don't know what it is. A fellow grower is also having the same problem. I am not seeing any bugs on my plants, I have checked morning, noon and night. But the evidence of something is present. The infestation is attacking the top half of the plants and they are attacking the small shoots. Its almost as if the shoots are getting bitten through to the point that they fall over but they don't fall off. They have a brown spot on the side of the shoot that has fallen over. I have tried several things from neem oil to murphys oil soap, and have even gone as far as Sevin dust and nothing is stopping these little critters. I have 60 plants that look they are in very serious trouble. I certainly don't want to loose this whole crop. Any help to point me in the right directions would be GREATLY appreciated. Im sorry I cant provide pics at this time, but as soon as I get my hands on a camera I will do so.
