The plant looks stressed and I can't figure out why.

Hey Growmie, Drooping, “tired”-looking leaves in plants around week 4 to 6, especially just before flowering, can be caused by a few common issues: Overwatering – This is the most frequent culprit. If the soil stays too wet and doesn't dry out between waterings, roots can’t get enough oxygen, leading to drooping. Underwatering – Less common but still possible. If the soil is bone dry and the plant hasn’t been watered recently, it may droop from thirst. Lighting Stress – If the light is too close or intense, especially during pre-flower stretch, leaves may curl or droop. Nutrient Imbalance – Around the switch to flowering, nutrient needs change. Too much nitrogen or not enough phosphorus/potassium can cause stress signs like drooping. Root Problems – Compacted soil or rootbound pots can also lead to droopy plants. To help narrow it down,How often are you watering, and what’s the pot size/medium?

Looks under watered and not enough nutrients try and water them every other day for a bit and see if they bounce back

From what i can barely see of the soil, it looks bone dry. Maybe, it's poor watering habits or waiting too long between irrigations... 1) Always fully saturate.. if soiless go further and ensure minimal 10% runoff. 2) wait for appropriate dryback and repeat. Never have water. Never superfcially water the top layers without ensure it gets wet all the way down and completely. This simple act should never cause problems with a plant. If it does, it is the fault of how the substrate is constituted. If it is wilting near end as it dries out, irrigate sooner... loss of weight or drying 1" deep etc are good triggrs to keep consistent with timing. Half assing the watering or spritzing the top makes some people feel useful, but all it does is train superficial roots. Superficial roots suck donkey dicks. The other potential for constant droopy plants in the absence of a lack of water or poorly constituted substrate depriving roots of o2 is your light. If providing too much light, this can happen. It may not happen initially, either. This effect can take time to present itself after the plant starts to receive too much light per day. If vege growth has notn stopped, the resulting distance between nodes is an indicator for your light intensity. They'd be very tight if providing too much light. If vege growth has stopped you have to rely on other visible indicators. being droopy for the last several hours every day would be correlated, too. Cycling in and out at end of day is not. most people get really weird wtih watering, so i'd wager this is the cause. If you deviate from the above 2-step process, fix that before doing anything else. If basic watering causes droop, there's not much you can do this cycle, but you can use more perlite or similar next time to avoid it.

That droop looks like classic overwatering or poor root aeration. Leaves sag evenly and have that “tired” look, which often shows up when plants don't get enough oxygen at the root zone. Could also be linked to a substrate that's staying too wet or compact. If you're in the stretch phase, they should be perky – so check pot weight, watering frequency, and make sure drainage is solid. Let them dry out more between waterings and they should bounce back.
