Wait until your little sprout has at least two sets of true leaves before you give it any kind of fertilizer. Even then start out with quarter or half strength mixture. I agree you should go organic, but if you want to use the MG that is surely up to you. Just make sure to start out a quarter strength so you don't burn the little guy or girl. I use Fox Farm's Grow Big for veg, and then Tiger Bloom for flower. If you wanna come check out my grow, the link is in the signature.ok so,the plant came up today, i watered a little this morning with tap water and have have it under light. but i just have it next to my window. and a small fan is blowing. when should i feed it miracle grow. or what should i feed it with?
