Seedling 2nd set of leaves purple

2 of my seedlings have purple edges starting on their 2nd true set of leaves. They are 6 days old. I planted them in soil that contains bunch of nutes but my third seedling is fine so I don't think that the nutes are the problem. Are they going to be okay? Hard to see on the image btw

Heres the pic

it's hard to see what you're talking about, they look ok to me. this is way to early to sweat small stuff. unless they start to look a lot worse than that, i wouldn't be too concerned

Its normal for the leaves to do that. My purple #1 from dutch passion were super dark like a black purple when they sprouted. My white widow X AK47 from shanti were violet under the leaves. With that said, you need more sunlight, and bigger pots. I'm not sure about the soil you are using either. GOOD LUCK !!

Ok thanks! I'll just wait and see how they turn out then
