3/6 seeds not coming above ground

Yep, I went through the dirt of the latecomers, and there were no roots developing, just pieces of what it used to be. In total, I have 2 GH Lemon Haze Auto going strong, and one Pineapple Express trying it's best.

Where the tap root exists the seed, needs to be pointed upwards. It then does a u turn and heads back into the soil while the sprout head, heads up and out, pulling the shell off as it heads for the surface. If you planted with the tap root pointed down, it is upside down. Cheers
