All 3 are going strong, with the Rhino taking the lead, Early Miss close behind. Likely the result of root training, but could also be a result of different strains. Watered without nutes based on leaf colouration.
End of week update - Transplanted the Black Rhino and Early Miss into there final pots. Didn't think they would be ready but it appears as if they were. I also started stress training all three strains.
