MY PLANTS ARE FUCKED UP! I have had this same problem with 3 plants, it starts out on just 1 branch and before you know it the whole plant is growing cabbages. My plants grow outdoors right next to each other and 2 that were growing about a foot apart developed this problem first. One of them was killed because it was a male, the same plant that's in the pictures, and the second has healed up for the most part and now looks quite nice but it still has this problem on older growth. The 3rd plant is looking much like the one pictured, so I decided it was time to stop guessing what the problem was and come to rollitup!The problem also tried creeping in on a 4th plant this year but I cut the branch off that it had started on just to be safe and it hasn't returned. I have tried pH 6-7 water for the last week and my soil pH is currently at an ideal range, but I have not noticed improvement. My plants are grown like any other outside with day time temps of about 75-80 degrees and night time temps of about 45-50 degrees. Please help if you have any clue what this might be.
