Sick Mother Please Help

So my Purple Kush mother has either some bugs or a growth on her. I am hoping that you guys could help me identify what this is so that I can take care of it. They almost seem like mini snails and there is a shiny sticky residue on the branches they are currently on. I pull them off and crush them (seems to have a hard shell), but they come back again. This is only on my Purple Kush mother and not the other two mothers which sit in a grow tent next to each other. I have included some pictures and any help would be greatly appreciated. Peace

Scale.

Safers soap will take care of them.

Wet

No, this is a completely isolated green house with now windows. I don't have any type of bushes growing around it and I am at the 32nd parallel
