Fast buds* Kosher Cake Auto & Green Crack Auto

Whats up to anyone who see's this. This is my first GD and I am still pretty new to growing this amazing plant. I am super excited for this run! it is a little ambitious with trying to cram 6 plants into a 3x3 but my goal is to absolutely pack this bish with giant stinky nugs. Hopefully being auto's it will be manageable but if it gets out of control, I will move a couple plants into the 2x2. This will be my 5th Run ever, this one being my second run at Auto's and have been growing for around 2yrs. Really hoping for a harvest for the books and some good memories. All Seeds were sowed directly into 3 gal fabric pots filled with pre-moistened HP Pro Mix and Dynomyco added. Used random jars/containers I found laying around to cover. About 4 days later all but the Kosher Cake #2 had sprouted with KC#2 showing up the next day. Plain water as needed and removed jars once the seed hull fell off. Right off the bat i am noticing the Green Crack phenos to be more vigorous and slightly ahead of the Kosher Cakes. Curious to see if this will follow through the plants life cycle. Kosher Cake #2 is definitely the runt of the group, spouting a day after the rest and appearing smaller than the others. Also when KC#2 first started to sprout it had a very dark color to both the stem and cotyledon leaves. Almost a very dark purple/blue. Not counting it out!
