i will say yes, i have had a male plant(jock horror) pop pistils after it was stressed a bit
not sure if they popped out of the pollen sack, but growth was distorted, so it was hard to tell where they began and left off
I don't think they can grow pistils out of the pollen sack. Only female plants become hermie when exposed to too much stress and you will have both female and male flowers.
I believe this can happen if I am correct in what you are asking.
You have what looks like a male flower or nanner that is also growing a pistil? Is this on the pre-flower? (which is where I think it happened with me.)
yea a pre flowering female. still in veg. its starting to look more like a female pre flower now though so im just asking in general. not due to stress though as far as i know. it was there before i topped it but it might have just not grew in all the way for a while idk.
