Skunk AUTO (in Soil)

First time I try Auto seeds by PEV Seeds (sent as a freebie to participate in a contest). I use 10Gal pots for the first time (normally I use 5Gal). And these are Cubes, so I decided to go with a modular support cage. I water the plant Tuesdays and Wednesdays by hand 1Gal of regular cold tap water. I feed the plant on Sundays by hand 1Gal of cold tap water with nutrients. Only in week3 of Veg and already Blooming! I hope the plant is big enough, (I normally would have given it another 2 weeks in Veg before inducing Bloom).
