He's been helping me on my first grow and his advice has helped me get to this point with no issues, I even trimmed them with no negative effects.

Those are both mephisto Genetics autos and my first grow.
Side note: I personally don't water the germinated seed again after a light pour after planting until I see life break through. Then, on Jpkindbud's advice only watered the outside of the pot so the roots look for moisture and establish well. My plants are veery healthy so his advice is good.
