they upped the Cal/mag in 2.0. I've not used a drop this grow! People often assume red stems is a cal/mag issue when more often than not, its genetic. Your buds look great!
Looks like your getting some excellent results
MC 2.0 is starting to stand out as possibly THE best 1part (single part) Nutrient that really only needs added cal mag (IF using high power white light LED’s such as Quantum Boards, or Cobs) especially QB’s tho.
My QB96’s cause this to happen naturally in most of my plants. They are not deficient
QB96’s at 160w each @ 20” or less will do this to allot of strains. My Sour Cracks did not exibit this tho, so I believe it is partially genetic as well. Only happens mid-late flower. Only happens with my 96’s. Only happens at 20” or less
Cool stuff! Makes things really pretty
