Welcome to the "joys" of growing genetically unstable auto flowers!
It is due to too many unstable auto flowers over an extended experiment with roughly 30 autos, that I decided to never grow auto flowering plants ever again.
I had more "weird" genetics over those thirty odd autos than I have had in growing "normal" photoperiod plants for the last 35+ years!
Stick with photoperiod plants, they are vastly more stable genetically, yield vastly more, are vastly less problematic to grow and harvest can be had using vastly less electricity. I too got sick and tired of waiting 3 months to harvest either runts, low potency or mutated flowers.
I personally don't believe autos are all they are cracked up to be, with most of the questions in this forum dealing with auto flowers and their problems.
I am hoping autos will fade into a distant memory soon enough, or the breeders lift their game and make a break through in being able to produce auto plants that perform equally as well as photoperiod plants. As it stands, autos are a long way off this goal.
Hope this helps,........ Organoman.
