Did I topdress too much?

Curious if anyone has seen this type of yellowing on new leaves. They do seem to grow out of it, but it's pretty intense yellow. No burnt leaf tips.

Organic soil mix I made. Topdressed with BAS Craft blend last week.

Thanks @Leeski I think the pH might be too high causing a Zinc deficiency. Part of the soil mix I made is coco coir (20%), which apparently can cause pH issues.

Going to try to water in a bit of Sulfur and see if the pH drop clears things up. If not, I have a foliar spray that has Zinc in it.

That's just my opinion though. Don't do it just because I said to. Research it.

10 gal. Don't worry, I've spent all day figuring it out, and my soil mixes def miss these ingredients. I get my compost local and they test it...shows low Fe, Zn, and Mg. Can't hurt to have this on hand.
I was just wondering about top dress. Smaller containers need more frequent top dress. You're good with every few weeks.
