First time grow, is she looking healthy?

[716legalgrow]

Hello! This is my first time growing. I have right now 4 plants. One is a clone, and I have been having problems with it. Can anyone help? I don’t know if it looks healthy, if I’m just overthinking it. Experienced minor nutrient burn few weeks back. None of my other plants have gotten it. Like I said, it is a clone. Last 3 pictures are from my seeded plants. All have been doing exceptionally well.
