Male?

The calyxes are stacking very unusually, but it still looks like female reproductive tissue. Could be from stress (eg extremely airy buds) but it might just be odd genetics if it's only affecting the one plant. Look at Dr. Grinspoon as as a strain that has long strands of calyxes with very little density. This form of flower is a throwback to early cannabis genetics/landraces before there was a huge effort to breed for heavy yields and chunky buds. Growing from seed, genetic quirks like that can still happen. Happy growing! 🌱👍
