What are the chances of survival?

So I dont really want to explain the backround as to why the plant is in distress but ill explain the conditions. The plant is about 8 days into flower and I last fed it on thursday right before the lights go on which is about 1030pm and they go on at about 10:30 am. Now I havent had contact with the plants since then and wont be able to again until about saturday. Now I find out the lights and fan and everything have been turned off for good on sunday so I want to know if the plant can make it from sunday to saturday in the dark and it will probably be around 50 degrees fahrenheit. Any chance? When i left it the plant was in great condition and im doing LST if that matters.

Thanks

heres a little thing I like to call a bump

the plant actually got bigger and there are no dead leaves or anything pretty freaking cool this thing is a monster although a male i think
