Advice needed

[Britfarmer]

Hi guys, I’ve noticed one leaf on every plant has a slight colour change & ive looked at all your other posts & advice & bought treatment for all that go near & updated my ph kits, I’m just after a second opinion on what u guys think of it & what action to take, thanks in advance, these are 2 weeks into flower on 10 weekers
