I'm not sure if I have the same problem but my tomatoes don't look very well either... the smaller ones have curled droopy leaves and the larger ones have curled droopy tops. They are all in the vented greehouse and I don't think I have overwatered or let them dry out. Some of mine have started to flower. I will try to attach a picture.
