I used Ocean Forest when I grew in soil for plants past the seedling stage @Cannafitter so I don’t know much about Happy Frog. I started using nutrients after 4 weeks or so. I don’t know what nutrient mix you’re using. Could be something you need to add or maybe a nutrient lockout for some reason. You could always flush her with a couple of gallons of water. That will reset everything and after that you can go back to normal feeding.
What is ph? You shouldn’t have to feed anything for at least 5 weeks in ff soil.
