Not looking good, some advice

ok so have flushed and the plant looks like its on deaths door step, dont want to loose it, SHOULD I JUST CUT IT DOWN? its on 50th day flower, more then half pistils have turned. as this is my first grow id rather have some half good bud then all dead bud. Definitely in need of some advice.

Leave it in absolute darkness for 48 hours.

Then cut it.

think ill leave in dark for 48 then cut, have no experience in growing, my set up is kinda ghetto, have cruddy nutes bought from some stealth hydro site, and ive got a few new little buddies started already. there are no fan leaves, the necrotic spots have started hitting the buds. Probably good to get it chopped and trimmed before its dead.

one more question, the strain is a indica/sativa called amnesia lemon, it says it would be 20%thc, how much would the potency be affected if cut down a couple weeks early, would a good dry and cure help.

k, thanks. so cloudy is good, i will check, if not will try and keep alive for another week or so. hopefully the trichs will be cloudy.

spots on the bud?

You are certain that it's not mold?
