The problem looks like its affecting just the newer leaves, not the big fan leaves lower down. So if this is a nutrient problem it comes from an "immobile" nutrient. That makes a Calcium deficiency most likely cause. Could this be possible?
Other immobile nutes which may be a problem Sulfer, Zinc, Iron, boron, copper, cobalt, selenium and silicon
