Thanks RBG, Duh!!!!!
I looked again at the ingredients for John's Recipe, the liquid fertilizer I use for the new and wee ones. It's rated at 3 - 1.5 - 2. Ingredients include fish, seaweed, molasses, humic acid. I use it about 1/week on the seedlings, and now the 3.5" pots giving them a nudge for growing.
