I'm using MG with good results, and I augmented the MG nutes with my own fertilizer tea. Just don't overdo it. You can follow the "Sunroom Grow" link in my signature for lots of details and plenty of photos. Eight weeks to the day from transplanting to first harvest.

jahoo, like you I also move my plants daily from the closet to the sunroom and back for lighting control with no hermie issues. As with any photoperiod-sensitive plants, the key is to not interrupt their dark cycle. The day cycle is much more flexible, since plants have to deal with partial shade all the time anyway, as well as with temperature changes.
