Plant is now about 1.75 inches tall, and is doing good, it also has 1 long root coming out of the bottow that is about 1 inch long from the bottom of the grow plug.... Notice the pics 1 of the 4 leaves is slightly brown and is slightly curled up. It almost looks like it got burned a little from the shell of the seed, does this happen ??? Also ph is close to 7.... Also have tin foil covering up the unused holes so no light gets to roots, is this good ??
