Imo it looks like you may keep the light too close, also seems to be a bit of nutrient burn on the tips of the leaves. Not enough to worry about, but worth mentioning. What is the plant getting for nutrients and what kind of soil mix are you using? Providing that information in the future is sure to get you some more... Helpful... Responses. Lol
The pot is too big because the tiny plant can be overwatered/over fed/over saturated. When the soil is over saturated, regardless of additional nutrients, it can mess up the PH of your soil and that can lead to endless problems.
Please feel free to ask more questions and provide as much info as you can, if you're serious about improving your grow
Cheers
