Well first off, LEDhead, be patient and keep yourself calm... smoke a bowl if need be, and realize, she is just a plant (please don't hate me), we all make mistakes and learn, that's the best part ... experimenting :)
Bubba Kush is a very lovely strain. She however doesn't swell as much as other strains. She is a 70-75 day strain. Most "plump" comes in at around 50-60% with more density filling in around 85-95% of the life cycle as far as I have seen. I have learned never judge my crop until 80% through, and still, be happy with the beauties you have raised ... if anything, they can be made into hash :)
Your roots could have been recovered, you have 30-45 day window remaining to fix your herb and you are right at your peak point.
As others suggested, your LED is a significant down fall and you have gone a bit happy with your defoliating.
Never the less, you learn and correct according to your grow. You are doing a great job.
