Alaskan purple auto

week 3 is a tough rn not gonna lie shes yellowing extremely fast and shes begging me for potassium. i was just giving her 2 tsps to 3 gallons of water. as of today (jan 8 2022) i gave her a feed of 1 and 1/4 bloom and 1/4 veg nutes to try to fight the yellowing. i honestly dont know if that was the right thing to do most threads i read just said to add some nitrogen but idk if dyna gros bloom and grow are meant to be mixed. especially this late in flower. either way its too late i already gave it to her i guess now all i can do is wait and see what happens. you can see how fast the yellowing is happening too.
