Its the first time im seeing this after growing several plants like this. It is only effecting this plant. I have 2 more gg autos 3 weeks behind this one in the same closet.

Ive looked over the whole plant with a loupe, both sides of the leaves and no signs of bugs. Its effecting the top half of the plant. LRM_EXPORT_373552832611122_20191018_185949756.jpeg
