In some cases it means you will have to water more because all that dirt absorbs the water very quickly and could transport it away from the roots. Just keep an eye on it. As long as you transplant correctly very little shock is realized by the plant. So you said your in your closet now. I would just make sure that light leaks won't be an issue, not that your light is leaking out but that an external light source could find its way through a gap in the bottom of the door or otherwise(been there). Kudos on the 600mh though. Don't have any experience with those nutes,
