That's not looking good. If you are determined to fruit it, do so out doors, and do not open that box around your grow area. It is contaminated. You might still get a flush, but the longer you keep it in the house, the longer the contaminates have to release spores that could make future grows difficult. It looks like maybe a combo of mold and bacteria, though it is hard to tell from that pic.
In my opinion, I would trash it and start again. Sorry brother.
