I was thinking bugs as well. Take you scope you use to look at your trichromes and look under leaves . You might see one of those pesty buggers. I use hot shot no pest strips in my room.pest stay far away accept for my cat once and a while when he want to catch a buzz. A magnifing glass will work if you dont have a scope.Dont make any sudden changes till you have looked for bugs!Maybe rusty will stop bye and give some insight?he has lots of experience.
