What am I doing wrong

Can someone please help identify what’s going on please any help would be much appreciated thank you,
Fan leaves are of one plant and buds are of others need help with both problems please
Second pic plant looks slightly more yellow and not as filled out as her sisters all of which are into their 3rd week of flowering using nutrifield ferts

First thing i would do is get some better pics in natural light, lights off with flash

Sweet bro thank you I’ll get onto that

Could be a phosphorous issue. Whats your pH running?
