still tho keep a close eye on them and check daily coz if it turns out to be bananas then u wana get rid asap incase you end up with pollen everywhere....
iv grew hundreds of plants and iv seen that before and to me its a hermie... some will dissagree but what im seeing is exactly the same as ive seen on other plants in the past...
see if you can take one off for closer inspection and try n post pics of that if your still unsure..
if you can manage that ,, and if it is bananas then you will see something that looks like a yellowy elongated coffee bean which will have a crease or line right dwn the middle...
