The "good" ones look like these, the bad ones look like Charlie Browns Christmas Tree. From the pictures I have seen the bad ones are all pistils and no real bud. One thing I read said the plant stops building on the main flower and starts stacking on the foxtail so they kind of look like a glove with a little palm and long fingers. I had one plant in the back that looked like it was flipping me off.

The upside is they had almost no leaves to trim, but I will see how they smoke before I declare them good or bad. Worst case I will only grow Kush strains in the  cooler weather and save the Haze's for summer grows.
