Should leaves be this yellow during flower?

[GrandmaGanja]

This is Bruce Banner strain, well into flowering. I know some yellow is expected during flower but this seems considerable. I’m using fox farm nutes, and have been adding some chicken manure and calcium magnesium as well but it doesn’t seem to be helping. I’ve dialed back the watering as well. The good news is there are a few bug buds coming in that are nice and deep green, but this yellow is concerning.

The yellowing has gotten worse after you added nutrients? Or remained the same?

Any damage done cant be repaired, so the yellowing is permanent. The changes will be seen in the new growth.

What's your nutrient regiment look like?

Initial damage was done after a feeding. We scaled back the feeding and it hasn't gotten worse.

Once a week give a half portion of Fox Farm Big Bloom. Last week I added a full portion of chicken manure and half portion of calcium magnesium (MAG-I-CAL brand), but we dont' normally add that. It was just looking badly.

Does this look like nute burn?

Also worth mentioning that there is a fair amount of 3 fanned leaves. Like more than half the plant.

It doesnt look like burn to me.
It looks like the opposite to me.
Looks a lot like classic nitrogen deficiency.
