Hi heaze2020, welcome to the forum
I can safely say in my experience that you can absolutely damage a plant from going indoors to straight outdoors (doesn't happen all the time but CAN happen)..that's why they always advise to sit new plants from containers into shade before full sun, it really can burn them, similar to how we would feel sitting in a darker room for weeks then being placed outside in full sun looking straight into the sky!
Not saying the superthrive didn't effect that I cannot say bud.
