Can someone please tell me what these colors mean?

As you can see in the pics, I have some leaves with yellowish/white striping on them. I have my lights mounted 12 inches above the canopy at 25% power... using growers choice e720. I’m using fox farm ocean forest with no nuteS added.

This is only the beginning of week 3. What could be the problem?

When I've had that happen it's been a function of my genetics and seemed to change nothing in the grow.

Nothing. Ignore it.

I had a similar look on some young ones I had, and I found out it was because I put too much fan on it..little windburn..started by looking like part of the coating was gone on the leaves.
I'm sure since they were growing rapidly in a few days they would have been accustomed to more air had I left them, but I turned off the second fan I had going and the problem dissipated. Although I probably could have done as xtsho says and just ignored it and they would be fine.

Appreciate you guys. I was definitely getting worried
