Leaf deficiency pic

Name this deficiency. I've been seeing it here and there but not exactly sure what it is. It looks pretty cool. I posted about this problem before but this leaf pic is a perfect example of what it looks like late in the deficiency stage. Anyone have this happen before and know exactly what caused it?

Well I figured since it was so distinct not much info was needed, kinda like a full yellow leaf is n deficiency. But it's in vermifire soil, was reported from a party cup to a 1 gallon pot the other day. Only given water, it's a few weeks old. Fed once with a 1/4 strength gh micro, bloom and grow. 1/4 strength calmag, 1/4 strength rapid root. Watered when needed with 6.5 pH water. It was a mutant seedling and grew wierd. Ended up shooting 6 tops after the first set of 3 blade leaves. Under 24 Watt Floros. Just really looking to see what the problem is since it's really defined and pronounced.

Also all new top growth is fine, some funny colors on some of the smaller leaves though.

It just seems like it's a "classic" deficiency but I have no idea what one, it also doesn't look like any nute burn I've ever seen in my life, I guess I'm just hoping for someone that has had this exact thing happen and know what it is and how to fix it. So any veterans that have seen it all, lemme kknow
