That's better!

Now clean up all that dead or dying rubbish laying on top of the soil.  You want to keep that shit clean!

Make sure you aren't over-watering.  The soil should not be sopping wet.  Your potting container should have drain holes in the bottom.  Use a measuring cup when you water the plant to figure out how much it can take without flooding out the drain holes.  The amount of water necessary will vary quite a bit depending on the plant's growth stage, container size, ambient temperature and humidity.

In between waterings, make sure you let the soil have a chance to dry out a bit and get more oxygen to the roots.  You should try to water at the beginning of your light cycle, so the plants can transpire more of the new moisture and allow for more oxygen to reach the roots during the dark cycle.  Watering just before lights out can contribute to the suffocation of the root system.

To get an idea of when to water, pick up the container.  Is it very light?  That's your sign that most of the water is gone.  A major warning sign that lets you know its time to water is if your container is way light and the leaves start to wilt or droop.  Try not to let it get to that point, but if it does and you catch it early, it won't be a big problem.  Over watering is a bigger problem in my opinion.

During the vegetative phase of growth, try to give the plant nutrients that have a slightly higher Nitrogen (N) component.  Most nutrient mixtures/solutions list the N-P-K content as a series of three numbers.  The first number is the nitrogen, second is phosphorous and third is potassium.  Once you get into the flowering phase, you'll want to switch to a nutrient solution that features a higher phosphorous (P) content.

Since this seems to be your first grow, go easy on the nutes.  Better to err on the side of caution by giving them too little nutrients, than to burn them with too much!

Good luck, and keep us updated!
