I keep hearing many growers saying different things, and I'm confused. Im growing white widow as my first grow, I have my seeds, and I'm using Fox Farm Ocean Forest for my potting soil. Some sources state not to add any nutrients until either the plant is about two weeks old, or grows its third set of leaves. Other sources state that you can add small amounts of chemicals. Now I was thinking that it's the CFLs (or other adequate lighting) that really generate food for the plants, and the nutrients are nothing more than the equivilent of vitamins for them. I am a first time grower, and with the plants being in such a sensitive stage of their lives I thought it would be better not to add anything until around the two week mark. So wanted to see if i was on the right track of just using water, soil, and lights for about 2 to 3 weeks ?
