You're correct every strain has it's maximum thc potential or limit, but as long as the plant is good and healthy the thc level doesn't change no matter the size of the mature buds. It doesn't go down as the buds get bigger. The lower "popcorn" buds usually aren't mature yet and will vary in potency.
I hope this helps.

Now is there any bearing to this? I'd really like to know because my friend could honestly care less well I shouldn't say that, but shes Rating: 5
