evertking Reviewed by evertking on . What is a good source of phosphorus? So I've got 4 2week old plants, kinda tiny...just put them under hps light today. I planted them in miracle grow potting mix...which seems to have low p. I think this could be a reason they dont look as thriving as id like them to. does anyone know a good source of it? Rating: 5
