It looks good. What strain is that? Looks like a squat chubby indica.
The one thing you may notice is the leaf curl. The leaves are twisting slight due to the pH being slightly off.
Possibly too low considering how dark the leaves are. It isn't a serious problem as the plant looks healthy. If you want to further the health of the plant make sure when you water the water/nutrient solution is ph'd to 6.3-6.5.
Good luck with the grow!
