According to this link it looks like N deficiency which is one of the most common problems with plants in bloom: Looks like it could also be a S deficiency or a K deficiency.

I figured it was a N deficiency but I just wasn't sure. Ill add a lil veg nutes and hope it gets better

Yellowing of the bottom leaves are normal when in flower. Bloom nutes dont have too much N as P and K are more important for blooming. Due to this a N deficiency occurs. If its bothering u so much just add some N. But u will be fine regardless.
