I have a miracle grow seed starting potting mix to start off my plants untill they outgrow the relativley small jiffy peat pots. After this I plan on transplanting to bigger pot but with a soiless medium. The soil-less medium will be 1 part perlite to 1 part peat moss and garden lime as an additive. Is this combo ok or good to have healthy plants? And am I going to have to add nutrients because its nutrient-less soil medium? Or is it best to wait till the plant starts to yellow?
From what I know so far you want to keep your plant green. As for the soil-less mix I think it is a few recipes on the site. I use pro-mix hp and love it so far. If you cant find what you want it is always Google. I'm sure you will find something on the topic.
