Read through the Grow FAQ section. There is a lot of info in there. When watering check with your finger. If the soil is damp on the top inch or so, don't water. Over watering is the biggest newby mistake. Every couple days for your plants is good. Use the instructions on the side of the nutes and cut it to 1/4 strength at first then work it up to full. At first you only will want to use nutes 1 a week or so. Once it got into flower a ways I nute on every watering. It depends on the plant and the nutes.
