Seedling look ok?

My very first grow and first time working with Promix and nutes, so I’m antsy about every little thing. Does this girl (Gorilla Glue #4) look like she’s going to get some yellow??

Details:
Autos, 3 weeks in, outdoor (slow cloudy and wet start) I’m using the KISS method, Maxibloom only at 1/4 strength. Doing Feed, Feed, Water. Ph 5.8-6.0

It looks fine man. You'll know when it looks bad.

Looks good to me. IME the new growth will sometimes look a little wonky.
