Devils letuce, I did not add anything to the Happy Frog. I just watered then 5 days later watered again. They started yellowing and I thought they needed nutes. Checked the runoff, pH, gave a small amount of nutes. Next they got water again, etc. After 3 weeks or so they looked pitiful. The pH kept rising, so I flushed with water. Week later, not responding well, so I got different dirt. Now I have gotten some help from my dispensary, as soon as they are flourishing again I will move them into Sunshine Mix #4 and feed them worm castings teas. They are already showing better looking new growth, but this dirt I am using I found out has chicken and cow manure...I MAY get a gnat problem so I am switching before THAT happens!
