Need [help] from any experienced growers

I'm in LA and it's raining, I wasn't having to much of an issue, my outdoor plant was definitely suffering from the lack of Sun

But things took a turn for the worse when I negligently left it outside. My plant looks like it has mold to my inexperienced eye, I know it's just damp as fuck now, and I immediately moved it to a sunny spot.

I have a few problems

• my plant is damp and moldly looking, and now has brown dead looking leafs.

• there's not much Sun to work with, and have lots of rainy days ahead of me these next two weeks

• I'm considering pruning the top nug now, and hoping my plant will recover in a couple weeks

I know I have a long road ahead of me, but I really want to save this plant, I don't care about the best smoke, the plant having a healthy life is my main concern. (I think these two things go hand in hand anyways)
