Based on what you’re describing, it doesn’t automatically mean it hermed — especially without seeing any bananas or male sacs on the plant itself.
A few key points:
Liquid squirting from a swollen calyx is often just plant fluid/bract juice, not a mature seed. Immature seeds are solid, not liquid.
At day 45 of flower, true mature seeds would already be firm and visible.
Your temp swings (26→22 day, 18–20 night) are not extreme and usually wouldn’t cause a healthy photoperiod to herm on their own.
What to check next:
Look closely at the nodes and buds (especially lower and mid canopy) for bananas (yellow, elongated, no hairs).
Check if the swollen parts have pistils — seeded calyxes usually lose pistils early.
Keep an eye on new growth, not old buds.
What to do now:
Don’t panic-harvest.
Keep conditions stable.
Avoid stressing the plant further (no heavy defoliation, no light leaks).
Without visible bananas or pollen sacs, I’d say this is very unlikely a herm. One or two odd calyxes can happen. If you start seeing actual seeds forming or bananas, then we reassess.
For now: monitor closely, but carry on 🌱
