Yellowing Throughout Auto

Long story short - I have an accidental experiment going here bc I'm an idiot and miscalculated the amount of soil I needed and ended up having to put this girl in some Happy Frog. I've read Happy Frog isn't the most nutrient dense soil for cannabis so I'm assuming this is a deficiency, just not sure of what. We are now around 50 days in and flowering. This looks like a N deficiency to me at first glance, so I was going to run out and get her some 4-4-4 or 3-9-4(since she's flowering), but thought I'd ask here first. So far she's gotten water only with the occasional compost top dress, no nutes Any ideas would be awesome.

I think you need some N for sure but that's just me

Thanks for the affirmation guys! I had some 2-4-1 kicking around that I fed her this morning, I'm ok with the 2 N since we are in flower (she might even need more nitrogen than that), but wish I had stronger P and K. Local garden center didn't have anything better in stock. Hoping this helps her! Thanks again for your replies!
