Well installed a fan and switched the 30w CFL with a 60 w standard "spotlight" bulb (to get some heat in there) and positioned the two 65w CFL's in a position better covering all 3 plants. Also removed about 70% of the big leaves from the one plant in images above that had yellowed a lot and had spots, which seems to have helped, at least the other leaves got greener and seem to have grown a bit. In addition I removed some of the larger yellowish fan-leaves of the "3-headed" plant to get some more light exposure at the nodes by their growing points.

The same goes for the third plant which I did not put up any photos of, it is not tampered with in other ways such as topping or LST as the two others.

The general update is that the plants dont really look better, but they do not look worse either, so it might help with the hotter environment and the fan installed.

My theory is that they most likely were stressed due to being both topped, LST'ed and transplanted into 3 different types of soil in one weeks time. and are hopefully recovering from that and will be fine with some time and care.
