Yellowing of plant

Hi guys just reaching out as to why I am noticing some yellowing of leaves on one particular plant. All 4 are Northern Lights feminized seeds. They are entering week 3 of flower. Could it be distance from lights? Any info appreciated.


Once plants go into flower they can show an N deficiency. Despite all being the same strain, they are different plants and will behave accordingly. Likely lighting has an effect, just that one pheno is more or less responsive.

Overall plant looks fine for about +3 weeks in flower.
