Not all seeds are created equal. :jointsmile: Some strains are very resistant to all different kinds of stress, some strains also like to have more nutrients than others. However some plants will hermie no matter how perfect the conditions are, and some of these will hermie more than others... nothing much you can do about it.

You really have to take each plant grown from seed on a case by case basis. Even feminized seeds of the same strain will show different traits. That's why a lot of people clone, because you know what you're getting with clones - they will be identical to the mother plant. Finish this grow, harvest, and re-veg your best plant and make it a mother, that would be my suggestion.
