This is just short of your requirements in a 2x2, I would find something that consumes about 150w to 200w and something not burple. A nice white lite around 3000k to 3500k maybe with a few reds. Dimmable would be nice.
What you have will work, but cheap blurple lights are about the worst LEDs you can get. No offence, I'm sure you didn't know.
In a 2x2, I'd suggest a kingbrite 240w 3000k with red. They are dimmable, more light than you need, so you can always give it more of it wants it. Also if you upgrade your tent to a 2x4, it would still be a great fit.
I’m a rookie but I’m leaning towards lack of light. They seemed stretched but could be the strain......oh now I see where you bought the lights, I’m leaning towards lack of light for sure now lol
