Hey, It looks to me like you are running warm CFL's... Correct me if I am wrong but they look a bit on the orange warm side.. If that is the case, those are more what is used in the later flowering stage. For Veg growth, they need to be a cooler and more blue spectrum.,
Also your plant looks a bit over/ under watered. Usually when it's over watered the leaves will curl under kinda like a dead spider, but upside down. She is wilting so, how often are you watering it? if you can stick your finger or a hydrometer in about 2 inches into the soil and it's dry, water it. Also a good way to tell is the weight of the whole pot. You will be able to get used to how heavy it feels when wet and when totally dry.
The bottom leaves look like a sign of an earlier fert issue but it seems to have been corrected. You can tell how healthy your plant is by the most recent leaves. A cannibas plant builds you a timeline from the bottom up. You have no reason to worry about your plant when it's the bottom leaves from when it was that age. As the problem gets fixed the newer leaves will look and be healthier and so on with the even newer leaves.
Fix the water issue either way that it is, and the light issue and you should be fine...
Other than that, it looks like a good healthy shade of green. be proud. Some people have killed their first plant by this stage! LOL Or when I first started out years ago My plant was the same size a month into growing that your seedling was in your first pictures! LOL
Good luck and keep us posted!,
