Minor leaf discoloration

[Bonzo]

Auto Gold Leaf in a Fox Farm Ocean. HGL 135 lights. Started these outside. Sprouted 23 days ago and moved indoors 5 days ago. Water only once so far until run off, and that was 6-7 days ago. PH was low at 5.7 or so.

Watered again today but barely any runoff

I’m not overly concerned but wanted to stay ahead of the curve. Are these leaves giving me signs of something that should be addressed?

They look fairly healthy. I don’t believe it’s a deficiency or burn. Is it possible that that leaf was laying on the soil. In the first pic it looks like it could’ve been. If so, that can cause minor discoloration.
