This is the first flower to open on a 7 pot primo yellow. It's about half the size I'm used to seeing from other chinense varieties I've grown.
I pinched and pruned for a while before letting my plants flower. Now, they're forming a lot of buds at once. Also, I moved them outside on the 1st.
Are primo flowers generally this small, or what might be the reason? All i can come up with is: the plant's stored energy is in high demand, being used for many new flowers. Also, maybe the bloom size correlates to the leaf mass (production level of photosynthates).
I'm reading some stuff about the source/sink relationship of carbohydrate translocation.
