I would not bet against the CalMag at this point. I am gonna do the daily CalMag add thing - adding it to the nutes as needed to keep the PPM at approx 1300. I started them into flower on 10/1 and they have not done much of anything in the last 2 weeks of the nute def. I will tell you that they ARE smelling much more pungent. I have to take a peek at the trichomes later today after my job interview.
