It really sounds over watered by the plant description. Since your misting the top, it would be hard to tell by feeling the soil surface since its always moist. Do what Polishpollack said, water through (that means till water comes out of the drain holes), then allow surface of the soil to DRY before watering again. It will always have more moisture under the surface. Remember, driest on the top getting moister as you go down, so make sure the top is dry before you water again. Roots need air. Without allowing soil surface to dry between waterings, they can't get it. If you loose this batch, start with something expendable. I'm going to suggest tomatoe seeds because their moisture requirements are the same. Just save the seeds from a tomato, clean them on a paper towel, then sprout & plant . Once you succeed with tomatoes with about 6 sets of leaves, you're ready to go on to the more precious cannabis seeds. Hey, its a learning experience. If you've never grown any kind of plant from seed before, better to learn with something cheap or free! Sorry, but you need to learn how to water to have a successful grow. This may seem like a waste of time to you, as I'm sure you're anxious to get your grow started, but if you will take the time to learn this first, everything will fall into place. If you have access to unlimited free bag seed, then it's ok to learn with thoes, but if you are buying expensive seed, try the tomatoes first to save yourself a lot of money.~~~PEACE!~~~
