if you have many plants throwing nanners, it is more often related to your environment, have you double check your timers schedule as well potential light leaks (since the days are longer I had to adjust because too much daylight coming from a window a few hours after the lights went off, my door is not 100% sealed.)
I have grown many spacebombs now (I made the seeds...) and not once have I seen a nanners and I did have problems a little while back with timers and also light leaks and I had many plants hermiing but spacebombs never did.
The one TGA strain I had nanners more than a few times were on my Agent Orange, ... but again, maybe they didnt like how hot I run my room.
