I have been feeding it but I dont have a ppm meter so being doing it by measurment. Only being using about half strenght from what hesi have been recommending. Perhaps I'll flush it with pure water and then start feeding from there. Easier to give more food than further over nuteHave u not been feeding it? looks hungry to me. Im not too cleaver with dwc, but maybe some folier feeeding wen the lights are out might help. Good luck paddy man, be a shame to lose this one too
