I was also suprised to see the cal mag def too. They bounced right back and havn't added it or had trouble since. I have up'd the nutes each week and the ph is stable @ 5.6. Towards the end of the week it rises slightly but no visible plant problems. The Sweet really made them stand up and salute!! List of nutes currently using:
sensi a + b bloom
sweet
big bud
purple maxx (only on two as a test)

everything is sound thank you all, pics coming soon.
