She's flying. The stretch allows more light to the nodes. But it's the leafs that use the light for energy so unless the leafs are blocking bud sites leave them alone. In a couple of weeks I'd be trimming the lower bud sites that don't seem to be growing as well as the rest. Basically the skinny small stems I'd get rid of if it's budding or not so it can transfer the energy into the bigger important buds. She's looking as good as any grow I've ever had.
