70% rh in flower, mostly 60%, ok?

right now, an hour after lights out, rh is 60%. week 8. tent 1.7x3x5 in a closet with a dedicated AC unit. peak after lights off is about 70rh in one tent with 4 plants. it gets down to 59 or so. ambient is 50 to 55 most. stationary fan at top over light, 390cfm fan out to attic, 190cfm in to bottom, oscillating fan on bottom, dehumidifier on bottom. vents open, hardly any vacuum. the 4 plants were fimmed and bentover with zip ties. the right side in the pic is the part i am worred about. front right will be done in 10 days.

i have an identical tent in the closet that is sitting at about 56rh. it goes between 49 and 62. i am not worried about this one. i don't know why it is less rh....yes i tested the rh. i have a govee wifi set.

is this ok. air flow seems good on paper, but the forest is super thick...i have never had a grow turn out like this. nugs and branches everywhere. rh under canopy is higher than above by 2 or 3%

can i make it 10 days before i cut one plant down....i think the extra space will fix things.

Your night temps are way too low for that high of humidity. I would be concerned. I believe the plants to the left are locked out and will die soon. Those main fans are dying fast I bet.

If you could get your night temps to 70 or a little higher it will be ok.

lol. plant on left got light burn when i added some ABI lights. it has been upset the entire grow. it doesn't like light or N. it have flushed the medium several times back to baseline. they all get the same feedings. i have another tent, identical with 3 more plants...also same nutes. no issues at all. the bud is fine on all the plants. the yellow plant is quite lush and green underneath. it is actually healthy, just a stupid thai pheno from OG kush genes on a NASC freebie. i gave it no N and it got more N curl....that is a pheno, not over nute. not N toxicity. i looked into it.

how do you know my night temps? they are not too low. night temp is 73f to 78f. it's atually hotter at night because i run an AC unit during the day. my govee provided vapor pressure and dew points...i am not even close to dew point. max temp is 78 and min is 69 over a 24 hour cycle.

I mistook your humidity with temp. I thought the temp was dropping to 59 and lower. Sorry about that. Looks like the temp and humidity numbers are fine.

for week 8 of flower it's ok? this morning they were up to 70% at lights off. i added a dehmidifier and an oscillating fan at the bottom. now, lights off, 71f with 61%rh expect it to stay closer to 60 now, but is that even ok?

Your VPD is about .8 or .9 for night time. That's the lowest range it can really go without getting into problems with mold or mildew. You are safe at these numbers.

VPD does NOT apply when lights are off. Have a look for yourself.

I wont argue about it. You do you. I'm happy with where I keep mine.

If you dont already have a bunch of fans in there, get some small ones to blow everywhere. Under your canopy and all your corners and you should be fine. I just harvested a plant ( at 9 weeks) with one to go with rh in mid 60's. I have 5 or 6 fans in my cab to keep things moving.
