Nah I’m pretty sure they mean week 7 since sprout.
Ditch it.
Okay, that’s extreme - but seriously, your plant is showing some deficiencies that Fox Farms can’t solve by itself. She needs CalMag, probably specifically the magnesium but both wouldn’t shock me.
She’s also going to want more phosphorus and potassium than FF can provide.
Easiest solutions are to get a bag of pure Epsom salts from your local pharmacy - just make sure it’s not scented or anything. Add at the rate of 1.5grams per gallon of water, but fully dissolve it first in some warm water before adding it to the reservoir.
Next up is the P/K problem. A monopotassium phosphate (your local hydro shop should have something like this) is the quickest, sure fire way to supply the boost she’s gonna need both now and as she stacks on buds. I have one called Mother of All Blooms. Fox Farms’ equivalent is called Beastie Bloomz - it’s a more expensive slightly less concentrated version. Amazon has unbranded MKP by the pound, which is $ up front but cheaper in the long run.
Your plants look good @MonkeyOatmeal36 and welcome aboard. Just keep an eye on these spots and try to treat as above.
Finally, it would be tremendously helpful if you fill out the “support ticket” - helps us help you if anything else goes sideways as you flower.
