hi hows you, i noticed in one of your pics that the leaves look like their having some kind of degiciancy, possibly nitrogen, you see the leaves that are yellow around the edges, this is either sign of over watering over a long time or some form of def, are you using nutes at this stage and if so what are you using, im on about the 2 plants in the 2nd pic, the plant in the middle and the plant on the left seem to have some form of def, the leaf from the left plant looks the same as the 2nd plant so id say its some form of def, hopefully someone will jump in and correct me if im wrong, im just trying to safe you have problems further along in the grow
