Barbara Bud is powerful indica cross between Shishkaberry and Afghani that eliminates symptoms without too much mental cloudiness. It has a fruity, citrus aroma with sweet undertones of bubblegum, and many patients have found Barbara Bud to help with pain, stress, and muscle spasms.
Bud size is affected by many factors like light intensity, strain, overall plant health and temperatures 🌵
It looks like your night temps possibly got quite low and they look like they've probably been slightly too wet 🌧
Another thing is that outdoors you really want early finishing outdoor specific strains so when they're in the early and middle of flowering they get good sun and by early-mid September they're done.
Looks like you'll get some nice flowers in a few weeks though 🔥🌻
