If she has doubled in size, in a week, odds are she'll be just fine. You might wanna read my sticky on stress less transplanting and compare to how you did.

I assume, this started AFTER transplant...yes?

I would use RO water that is bottled over tap water but I would use chlorine free tap water over distilled water anyday.

Stop giving her nutes, use 6.8 -- 7.0 pH water and use some rooting hormone powder. In this case, the damage may already have been done and you are just now seeing the results.

As long as the top portions of the plant are fine, odds are this will pass.

Good luck.
