1st big bud grow journal attempt

On the weekend of 420 I started 5 Big Bud seeds and 5 of the free seeds from amsterdammarijuanaseedbank.com. I lost two to premature planting in my 1in rockwool cubes. To reduces stress of transplanting i placed the cubes into cups of Glacier Gold organic potting soil. They have been growing in them since. The third pic shows a leaf that is folded over does anyone know what this might be from? It has happened to a few other leaves too. Im not to worried about it because they all are still growing extreemly fast. I made the mistake of planting in clear cups hence the duct tape. They are growing on sunlight sitting in my windowsill. Any tips/suggestions will be greatly appreciated.

your looking good so far man.
