Fox farms happy frog

Growing white widow autos. Plan on adding worm casti g to happy frog soil. Will i still have to add nutes. If yes when should i add. Any help appreciated.


I am a newbie as well but I have been using Happy Frog for my last two grows. You will need to start adding in nutes around week 4 or when the ppms drop down around 1000. Good luck! Let me know if you have anymore questions!


I use happy frog, and here’s what I do. Works great. I mix perlite, worm castings, and fox farm fruit and flower 4-9-3 per the instructions on the package to the happy frog soil. Then top dress with the fruit and flower after about 6 weeks. Then once a month after that, and that’s it other than ph’ing the water. I also use a little bio thrive bloom during flowering. All organic. I got 7 ounces of dry bud off my last GG auto.


What about adding cal mag
