to deep move it closer to the top 3/4 inch or so and your good...when/if it sprouts the shell part might still be on the "plant" you can just carefully take it of to let the light hit the little leafs..maybe 5 days
keep them as they are. they will still get taller so you might want to tie the down once they buds start to fill in...this will let the side branchs get bigger buds.
Why did you even ask if your not hearing what people tell you.. grow the skunk, pick out the males and grow the fems OR dont its your grow i dont give a shit
