All kinds of wrong here I can see you've got a pet food bowl right near your tent in the kitchen... You checked to make sure there are no bugs on your plant? Also are you drawing are from outside or are from within the kitchen when your cook and wash clothes cause your humidity will be sky high if not

I always start with environmental basics when looking at plant issues.

By that I mean;

1. pH ... nothing kills a plant faster
2. temp
3. humidity
4. air flow

Get those right, and it’s difficult to kill a plant.
You can damage a plant, stunt it’s growth, and diminish yield, but it can bounce back and forgive you.

The lights off pics, with the droopy green leaves ... when I see those I see an issue with the Big 4.

The leaves appear to have a nice green colour, so it doesn’t appear to be a nute issue.

Caveat: the pics aren’t super clear, but just the general attitude of the plants leaves says “environmental”.

No guys i have 2 fans to move air around in the tent plus a extractor to suck out the air. I cant draw air in from outside without raising suspicion. Definetly no bugs. I have kitchn extractor fans n leave the door n windows open when cooking.

Root bound.

How big is the fan extracting the air. Is your 600w air cooled what's the temp at the top of the plant versus the bottom. Make sure the air move at the floor level also not just blowing the tops around.
