Why the difference on these two buds?

Growing two Grand Daddy Purple plants. Same soil, lighting, nutrients. Why do the buds look so different? One plants buds are fluffy looking, and the other more compact.

Fluffy looking bud

Compact looking bud

Thanks in advance.

Just two different phenotypes, some are bigger than others. Some yield more than others. Some are short some are taller. Etc.
happy growing.


Iā€™m with Covert. Even on the same plant no 2 flowers will mature at the same time. It is particularly true of 2 different plants, even if of the same strain.
