Nute deficiency? Advice appreciated on outdoor guerrilla grow

[Sampsquanch]

Hey, just transplanted my girls outside into 15g growbags a few days ago. Soil is organic Promix Herb and Veg mixed with perlite. Plants are about a month old, one of which is yellowing etc (see attached photos). The soil has nutes that supposedly last 3 months, plants grew fine in it right from seed, but started seeing this 2-3 weeks back. Wondering if they just need some extra nutes or if its something more serious.

So the yellowing appeared before the transplant?
Doesnt look serious just like it wants a little extra nitrogen.

Yes it appeared long before.... One plant specifically.... Yeah thats what i was hoping honestly. I have some promix organic 7-3-3 fert plus some promix bloodmeal 12-0-0 so ill go give them all a feed this week.
