A plant that shows both sexes together is either a real, dioecious hermaphrodite or a female that was stressed from the beginning.
Stress is the most common cause of hermaphrodites.
The most common causes of stress, imo, are over feeding, heat, and over watering.
I had some THC bombs in flower, and I noticed one went hermie. I immediately put "it" outside away from the others, but apparently I was too late. It pollenated my females. If I try to grow out those seeds will they all hermie too? Or can I at least salvage this grow, and use the seeds from the females? Any help +rep, thank you.
I honestly doubt you had an actual hermaphrodite, that is a "hermie" that has an X and a Y chromosome.
Most stable varieties like THC Bomb rarely produce actual hermaphrodites.
What is more likely is that the plant was some how stressed and produced male flowers that do not have any male DNA. The resulting seeds will produce females that are likely to produce male flowers if they are stressed in the same way.
If you did get an actual hermaphrodite, which is very rare in indicas, the the seeds will produce females, males and hermaphrodites.
If you got a monoecious hermaphrodite which is more likely, then you have feminized seeds.
