Mid flower issues

Hi. Growing photo in organic soil. I’m 9 weeks in and 4 in flower and I’ve noticed leaf colours changing. Bottom leaves dying but think that’s normal but it’s spreading on one side more than the other. Been feeding Biobizz grow and bloom with some seaweed and cal mag and just adding a bit of big bud for a boost. Is it still hungry or is this all normal for later flowering?58CBDF1D-55D4-4D1C-897E-AABA51269AB1.jpeg
