Thanks for all the suggestions. I did move it out of the GH today and examined it carefully like NEEDRAIN suggested. Found two more of those green catapillars I've had problems with for a few weeks but nothing else. Hosed it off good and put some organic spray on. Will Followup with the soap recipe if that doesn't work. And then move to the stronger stuff Weedwhacker suggested if plantladyln solution doesn't work. I'm squeamish about those critters. Yuk!
Thanks for all the ideas!
