Whats the humidity? This is an auto right, given its 20/4 lighting? Checking your runoff ec value will help tell alot. Its helped half the time I had issues. This is called drain to waste coco or dtw coco.

When checking runoff, give the same runoff you normally do as thats the most natural accurate test. If no runoff or not enough to test thats the problem probably.

80F is great. Mine is 80-85F and 50-55rh.

yes he mentioned its an auto, said it was planted may 12th iirc, I've heard 80 is a little high for most grows, does it work well for you?

Humidity is low during 40 the day..have to get a better humidifier and when lights go off at night the whole tent goes haywire as I lose the humidity 65-70 need a better dehumidifier

if possible I would connect the humidifier and dehumidifier to another source of power so it maintains humidity during night, even if it isnt perfect humidity

If this is all coco coir and perlite, this is the issue probably. Bet money or partly the issue. I didnt have enough runoff and I was in plant problem section forgetting to check runoff.

Should be equal or only a few points higher in ec. Ex. ec in 1.8, ec out 1.8 or 2.1.

Feed atleast twice a day or whatever prevents drying out. It can and should lose some moisture which is different than bone dry to the touch.

The plant is in limp mode probably and will finish a little late if thats ok. More light in the 600-900ppfd range in 24 hrs will help, its counter productive to give an auto dark time.

Especially if its not needed. It more often than not is beneficial to autos.

I dont know about all the talk about dark time being beneficial to autos but people compare it to I think cabbage grown in alaska under 24/0. Im a believer im that idea.

Wait im not sure what you mean, its 40%rh when lights on then it goes to 65-70 at night?

I was also worried about high rh, those buds, I hope im wrong but they just have that infected look. Id take a close look inside a brown cola and take a smell and smell for mold.

My rh never passes 60 and its packed, I used to have that swing at lights out too I have no clue why it stopped. All I know that time I severely overpacked a 2x2 and got mold.

Thought that was mostly why the rh was swinging being too packed but yours is not packed so idk whats making it swing. 24/0 lighting should help stabilize it though.

Yeah like I said problem I have is I can't put my lights anywhere near 100% as my temps would go into the 30s.
The humidity at night when lights off goes to about 65rh I would say...I do use a dehumidifier but it doesn't cut it

So salt build up is a given here, it spikes in ec when is dries as it loses water so its just sitting in salt getting no water. When feeding to runoff you want runoff so it flushes that out.

It already spikes as it dries even ever so slightly, not bone dry but still loses water immediately after feeding.

I feed 8x a day and it stays in check. Probably slightly higher in the pots the ec, but when I feed, its so often and well that it reads back the inflow.

So I need to give it a good watering? Until it comes out of the bottom?

Buy a better one and also try and place it as high as possible since humid/hot air goes up.
Humidity should never go above 60 during flower.
