Looks like a magnesium deficiency. Do you give it a magnesium supplement like cal mag or epsom salt?

Leaning to the latter because the first two are rare

Could be any of those 3 for sure. I think Magnesium deficiency is more common if the soil isnt built correctly. Could also be a PH issue locking out nutes. A couple tablespoons of epsom salt top dressed wouldnt hurt anything to find out if its Mag.

They look hungry. Make sure your rootzone hasn't gone acidic. Keep pH at or above 6 in bloom. I dose epsom salts once a week at 1 gram per gallon. Do not dose with epsom salts if the leaves are dark green.

Instead of salt can I start adding cal mag?, I feed food, food, water. Every second day. Would it be best to add cal mag to the water or food?
