No, they're not going to get transplanted again until they go outside. I started a little early this year because last year where I live we had a very early winter and it was a nightmare getting them to finish flowering in sub 50 degree weather. Had to build a green house around them basically and keep heaters out there at night, then wake up early and turn them off and remove some plastic tarps so the tunnel I built could air out before the sun heated it up to 90+ degrees.Coco is complex lol... soil is a little easier... at about half and half soil/coco... I honestly don't know how I would treat it watering and nute wise, my gut says more like soil? Are you transplanting again before you go outside?
