Is my plant where it needs to be at 2 1/2 weeks old from seedling. It's been under 1 42 watt for 2 weeks. Just added another 42 a couple days ago. I saw another grow at 3 weeks and I'm nowhere near that's guys growth. Been adding nutrients less than half of recommended nutes schedule. Thinking I should add more nutes? Lights? It's in a 5 gallon bucket. Maintaing 5.6-6.0 range in ph. 73-81f. 53-63 humidity.also, notice the first set of leaves has brown spotting. Figured it was calcium Def. So I put 2 tsp cal mag. Hasn't spread since so I guess it did the trick.

Your room conditions are really nice. I think the problem is a lack of light and using nutes. Each plant should have at least 150W of lighting optimally. And never use nutes until the plants has 4 sets of leaves, it looks like yours just sprouted the 3rd set so it's still too early. I would also try to keep the roots away from any kind of light, looks like they are currently getting light in the pictures.
