Hermie?

The efficiency of photosynthesis is significantly influenced by temperature, primarily due to its effects on enzyme activity, plant metabolism, and the physiological processes involved in photosynthesis. Photosynthesis is facilitated by enzymes, particularly RuBisCO (ribulose bisphosphate carboxylase/oxygenase), which catalyze key reactions in the Calvin cycle. Each enzyme has an optimal temperature range where its activity is maximized. Low Temperatures: At lower temperatures, enzyme activity slows down, leading to a decrease in the rate of photosynthesis. In summary, the efficiency of photosynthesis is closely tied to temperature, influencing enzyme activity, plant metabolism, and water availability. 60-64F not warm enough. Until last week you were at 70rh% too wet. Cold temperatures can cause cannabis plants to become hermaphrodites. Hermaphroditism is a natural response to stress that allows the plant to reproduce in dangerous situations. Cold temperatures, especially sudden drops, can shock a cannabis plant. Cold weather can also slow down a plant's metabolic processes, which can lead to poor growth and development. Bump here up to 77-80f, keep rh below 60 for sure in flowering.

The first pic does look at bit odd... female preflowers don't multiple. There will be 1 calyx per branch at the base. You have lots of time to allow it to grow out, be certain, and remove it -- or whatever you choose to do. It won't have viable pollen for a long time.

Cannabis can do some strange things at times. When you go chopping on her she will do different stuff, sometimes hermie. Genetics plays a major role here too. Crappy breeding selling off first generation chemicly feminized seeds. Anyway look at them and in a few days they’ll share their true colors. Hope it helps.

Not great pictures, but pic one has me very worried about the possibility of being a hermie.

Does not look like balls to me indicting a hemi. just new growth from pinched nodes. But monitor it till you feel satisfied. Can tie a red pice of string on the area so you don't loose it in the bush of plants in the tent. Female calyx will have a pistil coming out of them or a white hair, they will be teardrop shaped and tend to point upwards. balls on the other hand are shaped like a coco pod and they have a very small stem connecting them to the plant. They also tend not to have any hairs on them or trichomes.
