Nothing looks unusual. Seedlings can get so tall that they need temporary support.
It's very important to have a thermometer and humidity gauge. They can be had under $10.
There are free apps to check the amount of light, and calculate that vs your hours for a DLI(day light index). I use Photone, and at this stage I'm at 20 DLI.
How many hours do your lights run? I run 18 hours on 6 off. Some run more hours, but I'd recommend at least 18.
I also run an ultrasonic humidifier in my tents. They start in the $40 range and go up, more expensive ones have controls that attempt to maintain a set humidity, vs cheap ones that just have continuous high or low output. The relationship between temperature and humidity is expressed as 'VPD' vapor pressure deficit which is the difference between the amount of moisture in the air and the amount of moisture the air can hold. Too much humidity causes rot, too little stresses the plant. This chart shows ideal humidity for temp at each stage of growth.
I set my lights first, then add humidity to reach the desired level. In the winter I've always had to run a humidifier in my grow rooms.
I also question your container size; Autoflowers don't like the stress that transplanting causes, and I start mine in their final container.
Some growers do get excellent results in containers as small as a Solo cup, but because of the small amount of soil they must be carefully and continuously watered. I am more of a set it and forget it grower.
Nutrition also is more critical in a small container because a small amount of soil can quickly get depleted. I grow in organic soil in 5 gallon containers. The soils I use, Roots Organic Lush, and Stonington Blend can be considered capable of 'water only' grows, but I do add a qtr tsp of Megacrop per gallon after the first 2 weeks.
Too much water, fertilizer, or light will kill or stunt a plant much quicker than too little.
