Iron,zinc deficiency ? Or is it calcium my pH is 6.8 soil

Looks like rapid growth to me. A bit far away but don’t see anything out of place from here.

I’ll put a better picture on later I’m not home right now but up close it’s yellowing between the veins on the blades of the families on new growth and slowly was working its way to older growth leaves I added a iron supplement I made myself with highly acidic water and a hunk of iron that I repeat to an acceptable level and it has bounced back pretty much since then so I’m guessing it was iron the soil pH is spot on 6.8 right now I’m growing organically usually I just water with ph 6.2 to 6.8
