Can it do that from continuously rubbing in the same location then?Looks like damage from the edge of your bucket to me.
Think what your seeing is just the hairs they seem healthy to me I’ll put another pic on... I know they are stretched but just got it under a stronger light todayI would be more concerned about what appears to me to be a white powdery substance on your leaves. May just be the picture.
I can see tiny tiny white dots on the leafs tbh but it doesn’t look unnatural to me as you have too look dead close to see that. But I’m far from an expert, what do you think this is then?
