Would make sure it's healthy and recovered from the change of medium, which will likely take a couple of weeks. Might need to raise the lights, and ease-up on direct exposure to the fans till she starts uptaking moisture from the soil again. Might even need to cut-back on nutes till they are acclimated. Adding Superthrive might burn virgin roots (virgin to soil, that is..) so use care.

Like Image said..the longer the veg, the better foundation (health, strength, vigor) you'll see in flower.
