Fan leaves turning yellow

[Jimmy Dickskin]

I'm fighting this battle that maybe doesn't need fought. Once flower started yellow fans leaves appeared only on the larger fan leaves. I tried some N and also used cal/mag. Been about 2 weeks. Seems like it worked briefly but now more yellowing than before. It is well into flower so maybe it's pulling nutes? She's a big girl , that's a 2 gallon water can.
For 2 gallons I use 1 tablespoons Alaska FF and 2 tablespoons of tigerbloom every other watering.

Could be under canopy bit humid not absorbing light the plant is doing itself a favour

Yes, most of them are more or less under the canopy. When it starts to pull the nutes to the buds during flower will it be the larger fan leaves first ?

When I grow in containers, I always toss a few slow release pellets into the pot if the plant is looking hungry. Yellowing leaves is a sign of a nitrogen deficiency, almost always. The plant needs more nitrogen.
