I have 1 plant growing, bout 3 inches tall, in MiracleGro potting soil mixed normal dirt. I need to know what fertilizer is the best for growing. This is my first time growing weed and I planted the seed in the ground and it grew2 inches and I transplanted it in a pot mixed with 35% MG and 65% dirt. I need help because I've already planted 4 more seeds in this mixture. BTW it is an outside plant
