What is the best rule of thumb to fertilize seedlings? Mine are 1 1/2 " to 3" tall. All have true leaves or more. I was considering a 1/4 strength mixture of MG Bloom Booster. I used MG last year with good results. I simply forgot when I stated the process. I did check FAQ and Suggestion and did find what I needed. Also is there a benefit to eliminating the original two leaves once the plant has multiple sets of leaves? Thanks.
