Help! Leaves curling

I would take some of the 4" flex duct you have, and put it through the port you show in the picture above, and make it into a U, so no light gets in/out of your tent.

If your humidity is still a little too low, you can add some tape over half of your exhaust duct to reduce the airflow rate even more. I do that in my drying room to reduce airflow and extend my drying time.
Just added tape to half the duct running into the tent. What do you mean make it into a U. I opens that pocket up to reduce suction

Just opening the pocket is fine for now, but once you get into flower that opening will let light in, and wreak havoc with your plants.

Unfortunatly im bad at explaining, and I dont have a good picture of what im trying to say on my phone. I will get you a picture today of my tent when I get home from work.

Place that hygrometer near the canopy not directly on your lamps. Zip tie it to a frame post so you can slide it up or down the pole.

Also using FFOF


Edit - IME, FFOF runs great on its own thru a 5 week veg (5gal fabric pots).
Then I top-dress with appx 1 gal (1") of FFOF and a little bloom booster on week 1 & week 4.

ok koo i get It now, but what’s the difference from running it over the top of the tent vs how you did it
Im not sure what you mean by running it over the top? I have my exhaust coming out of the tent up high, and the passive intake down low. That way the fresh air coming into the tent gets drawn across the plants, then up past the light, taking the heat and humidity out of the tent through the exhaust.

In the picture you posted your exhaust is coming from the top of the tent. You need to get air into the tent so your walls dont collapse like they are in the picture.

In post #59 you showed a picture of a slightly open port to help reduce the suction. What Im trying to explain and show is that you need to get some kind of light trap into that open port so you don't screw with the plants light schedule once you put them into flower.

In my previous post is showed my solution for this with a 4" duct placed in that port to block the light.

I hope this helps.

Ohhhh okay i think i get You, your saying put a piece of duct into that open port so i can Get more airflow and i wont have to worry bout a light leak.. it doesn’t have to be hooked to anything.

Exhaust just like you have it - pulling warm air out of the top of the tent.
@becasueracecar09 is telling you to add more duct tubing for intakes at the bottom of your tent pulling cool air in.

Your air flow should be passively pulling cool, fresh air into the tent down low where...
...the cool air is circulated (by clip fans) through your plants. The air will be warmed and....
...will rise to the top of your tent where your fan will exhaust the warm air out the top of your tent.

The curve/hook in the duct is what serves as the light break. Just need about 24" of duct.
A black woman's nylon / stocking or similar (edit - rubberbanded to the opening) will knock the light down a bit and serve as a light dust filter. Just make sure to tell the owner of said stockings before you destroy them. There were consequences in my house! :cuss::bigjoint:

:lol::lol: Thanks for the extra feedback... stocking sounds like a great idea

Yeah you really need extraction in there to help with the humidity, and you need the air exchanged for the health of the plant. That light should be enough for a 2x2 area at most. The plants don't look terrible you likely just need to dial in a few veaconditions. They need air exchanged, and they need air flow. Look at your temperatures at the canopy level as well, with LED you will be fine anywhere between 78-82 or so at canopy.
How many of us over 60 are using pot to help us stand the pain that we endure each day ?
