Hello all..relatively new grower here. I have 4 plants going. 1- 3 bears OG , 1 - Heisenberg Special and 2 mystery seeds. They all sprouted in ffof 4/9/07 in 5 gallon smart pots under king led 800w. I had to move my grow tent in the basement and it went from 35-45% humidity to constant 80% humidity. I'm pretty sure some of the plants have root rot because lots of leaves are dying off, but it could also be because it's close to harvest. The pots take forever to dry out. The one that has me concerned the most is the 3 bears og. I'm just wondering is it safe to just let them finish flowering or do I have to chop now? pics of grow below.

.... whoa! 80% is bad news over time, mate,... makes for stressed plants, they can't cool/transpire very well in those condition,.. this in turn will adversely affect nute transport, including P.... I see heat stressed leaves, (curled on edges),...lowers look maybe more like N defc. some of which is normal at this stage,... mid to upper yellowing and necrosis, most likely P defc.,... (Mg doesn't ususlly hit this high up, nor cause that necrosis until well advanced),... another concern is mold with that high RH,.. gotta get that down to under 50% RH,.. what's the temp's in there?
Hey Waira, thanks for the informative reply!! temps right now are at 72F. That is probably as high it's been since we just had a 101 degree F day. I have added more pictures of the grow without the LED on for easier inspection. Just want to know since its late in flower if I am able to ride this out? won't be able to move these plants anywhere, live in a city and would get stolen real quick if left outside.

temp is fine, RH% is not,... high RH% make water evaporate poorly, so poor cooling, and since the whole transport highway runs from the roots up to leaves,.. water drawing takes nutes along with it,... they look pretty good all things considered,.. Very nice buds! 
... and even I would crap a pink bunny if you got almost to harvest, or after it, and had mold F' you over at the last minute! 
If you have the $, get a small dehumidfier/AC, rent, borrow, whatever!.... drying will be a disaster for sure in that high RH%, anything above 60% will slow it waaay down,...the longer it lingers on the rack, those first few-several days, it's highly vulnerable until water content is reduced a great deal,.... temps should be below 75 (70 is best), or terp's loss will be pretty bad too,... but now, it's mold watch! It tends to start from inside out, so watch very damn carefully for small/sugar leaves that look wilted, off color from the rest,.. tug at it, and if it comes right off, bud rot is active,.. then, it's about treating like a gangrene infection, cutting away everything hit by it and some extra along the margins that are spore loaded already,... 
shit-shitty-shoo,....
