Nutrient deficiency or normal ?

I have this plant, about 4 weeks into flower. It’s got the most trichromes compared to the rest. It’s also starting to yellow on the lower leaves. Is this normal, or hinting towards a nutrient deficiency?Ooo

That looks like normal yellowing on the bottom. If it was a deficiency the newer growth emerging from the top would be affected. The larger fans will probably continue to yellow as they develop/ripen. Don’t sweat it; plants appear healthy to me.

your quite early into flowering, you could get away with a Nitrogen feed to give it a boost. leaves can yellow verry quickly. your going to want to pull those yellow leaves off, dont want the risk of disease . but looking real good
