Likely something else. Like when I stressed out two plants last year due to having to clear the tent for a seed run of IBL Durban. Nanners in both halfway through flower. This is a stable strain. Grown before by me and others. No problem until then. I knew immediately why and who caused it. This is important if a guy doesn’t want it to happen again. At least in my mind.
Durban turned out perfect. Not the two beautiful Tillamook Strawberry.
i am not spraying any plant in flower with bud period. end of story. unless dealing with a bug issue. unless you are a known breeder with experience Id layoff comments like that.
Changing the environment significantly. You can do it with temperature changes, poor outdoor lighting or a million other things. It’s the survival mechanism for cannabis. If it sucks now maybe next time.
Be aware that the exposed stamen ( banana dick ) doesn’t need to open to pollinate nearby buds. Even picking them off.
Probably environmental, irregular lighting ( red indicator lights ) or genetics. This will give you a chance to scrutinize your grow area at “ dark “ time and hopefully correct. High temp , wonky feeding , light stress are also reasons.
Mother Nature can also trigger a Rodelization ( survival tactic to preserve line ) and try to self preserve plant.
Had a few “ breeder “ issues myself with unstable offerings , makes One wonder about their ways of seed production.
