I transplanted today into the 5 gallon. You are correct, it was root bound. I picked up some Earth Juice bloom today as well as a timer and black/white mylar to seperate the closet space I have due to having 4 2 week seedlings in the same closet. I will start flowering tomorrow. I still have the magnesium thing going as can be seen on the picture of the leaves. Is it important that I don't go into flowering until I clear up the Mg issue? I have been folliar feeding for the past week.
