When they're born?
The first seems pretty good!!!
The second plant is tall and the internodes maybe are too distant. Perhaps she doesn't receive enough Sun.
Well, in vege you need more N so a NPK 7-5-5 is good. When your plant is in bloom you must use more P and K and less N. N is very important in vege but in flowering it can delay the bloom.
P.S. I'm sorry for my english but i don't speak it very well (i'm italian out grower)
