I'm a little confused about pearling. Is a plant pearling when a there's a stream of bubbles coming up or when bubbles stay on the plants. I've noticed that when I prune plants a stream of bubbles will start to come out. I'm thinking that this isn't pearling??
 
I thought the bubbles only held on the leaves cause it was letting out such little ones it manages to hang on there for a while...
