Looking at the pictures are 2 plants, both same genetic I bred, Golden Lemon x Sour Diesel, both were germinated around 50 days ago. In my experience, a male preflower always show first, and always have a "stem". IF the preflower looks like the male below, then later shows a pistill, it will hermaphrodite. My experience completely and this is why if I germ twice what I want. Then I can be picky. Another thing that allows me to be picky is working with regular seeds that allow me to make more.
