Alright, did as you suggested and transplanted. A lot of the soil fell away and some of the roots became visible in the small shape the soil was held. I massaged a decent amount of soil away, so the roots are holding in an area a little less than a solo cup. I purchased some soil without any nutes in it at the gardening store, as well as some neem spray. I misted my plants with the spray (no more than twice).. Things seemed to go okay, so I have my fingers crossed that I won't see any more damage other than a little signs of stress from the intesnse transplant. The soil that my larger plant is sitting in right now is Fertilome Ultimate Potting Mix.
