I agree with others, this should be a separate observation each time you interact with the individual (general recommendation is 1 observation/day unless something serious changes like metamorphosis, predation, etc.).
You can link the observations via comments/notes or observation fields.
I am not sure how this situation is a paradox though, so it might be better to have a more descriptive title.
There is no paradox here. iNaturalist is for uploading observations of organisms. The organism may still be the same but the observation, even one minute later, is different, hence the importance of being as precise as possible on the date and time of the observation.
You can link observations of the same individual to each other by placing a URL in the ‘Notes’ section or as a comment, which is especially cool if you have been observing the same individual in different life stages, but the differences in life stage by definition show that we are talking about different observations, which in this case happen to be of the same individual.
Edit: As I was typing @cthawley also placed a reply in the meantime with almost the same ideas and wording so my reply may have become redundant.
Wow, what a great series that is! By just a quick scroll through the photos, we can see that it consistently flowers precisely in March across the many years! Brilliant example.
