sorry to say this but sheis a gonner, if not it wont be much of a yield. Can i ask if that is PVC lining the walls? when the heat and light reflect off of PVC it creates poisons which are not good for plants, Im not sure what the problem is, because that went FAST. but its something serious, check into your reflective lining, never use PVC for that, use PE. If its overwatering you really drounded them. One more thing i did notice but cant believe it has to do with it but did you cut all the main fan leaves off of the nodes? because i cant see a single one! Man i feel sorry for her, what did you do????
