Is this a deficiency, toxicity, or normal for this strain?

Growing two autoflowerTangerine Dreams under SP150s and using the nutes in the pic below. Is the yellowing around the bud nodes and tips normal? I assumed I was feeding too much nitrogen at first, but now it seems to have gotten worse when I stopped giving nutes.

thoughts?

Looks to be light burn..

Raise or dim your lights if possible
