Hello fellow farmers this is my first real grow and i was just hoping to get a lil insight and direction. Just transplanted about a week ago started noticing leaves yellowing a lil on a few plants. My first thought was magnesium deficiency but not really sure. Growing some Kosher kush, Purple mendo, GSC and Granimals in coco using General Hydroponics Floral series. The room is sealedrunning co2 with 8 gavita lights, 4 4x8 trays 2 with 12 5 gal bags and 2 with 24 3 gal bags. Thanks in advance.
