I have grown church before and my suggestions are:
Give the plant room to grow. It wants to be a bit bushy.. I would also prune the lower growth as the lower branches won't get light on the buds.. They will be like popcorn.. Great plant.. Give it a good 9 weeks of flowering. Don't veg forever as it is gonna put on some size (3x where it is at veg). Also, make sure to use tressling or stakes or something to support the branches.. The colas will be large enough to bend the branches if you do it right. I actually had one snap on me under the weight of the cola... and it was on the side...
