All in all to me they look pretty healthy.
I’ve come to the conclusion that if you want perfect leaves that never discolor plastic plants are to only way to get that…but then again I despise plastic lol.
Go easy on the nutrients early on and usually with a good soil like what your using they generally don’t need any additional nutrients for up to 2 months so unless you see a need due to her look (leaves etc) I would just water her for awhile. The 2 spots on that one leaf could be from splash when you watered.
Which Fox Farms soil are you using? That can make a difference for you moving forward on how to feed etc.
As Purp mentioned above you wanna keep the soil Ph in the range needed.
From what you posted you are / will be feeding them General Hydroponic nutrients. Which ones? That also can make a difference in how you approach things moving forward. If the nutrients are salt based chelated etc (not natural but made in the Lab) there are things you will need to do to monitor for a successful grow to finish.
And as purp asked what is your light source and how far away etc.
And welcome to the forum and good luck.
