2 seeds, same strain, outdoor...yellowing fan leaves on part of 1 but not whole plant?!?

Appalachian gold, both put outdoors too early and revegged... fed ever week or 10 days with ff grow big then terp tea and dr earth and compost tea... mainly wondering why the fan leaves on one plant are yellowing bad, but its only certain branches of said plant... any ideas, both are like 3 weeks in flower, in ground and very vigorous....both have been fed the exact same

Hey man, so normally I would say it looks like a bit of an N deficiency, but those spots look a bit like septoria to me, so perhaps something fungal, especially as the spots seem to be worse in the deeper branches.

Are you PHing the water you are giving them? Could be a lockout if there is sources of N.
