Around the apex on the 2nd picture, it looks like a male appendage. Rest just looks like it started to flower then re-vegged. Which could explain the naner, I wouldn't trust me though.
"Cannabis will not stop flowering if the lights are turned on for a few minutes once or twice during the 2-month-long flowering cycle. If a light is turned on for 5 to 30 minutes—long enough to disrupt the dark period—on 3 to 5 consecutive nights, plants will start to revert to vegetative growth."
"Less than one half of one foot-candle of light (0.1ppfd) from sunlight will prevent cannabis from flowering. That is a little more light than is reflected by a full moon on a clear night. Well-bred indica-dominant plants will revert within three days. Sativa-dominant plants take four to five days to revert to vegetative growth. Once they start to revegetate, it can take from four to six additional weeks to induce flowering again!"
Good luck,
