this late in the game i wouldn't bother scroging. it would be too much work and might damage the plant. id work with what you got or add more stakes. dont be afraid to use a a lot ties. when you tie up the plants dont tie to the plants always tie to a stake or something thats stationary. be creative. next round id definitely scrog and if thats not enough add another trellis on top as she grows taller. good luck!
