one of the things that i ran into by accident was that the CFL were 2700k when for growth they should be more around 6500k. the cheap ones are usually the 2700k ones. just wondering if that might be an issue for you later on. I put those babies in my grow room i have about 7 6500k CFL my plants are loving them.

over watering can be an issue and well it takes a while to get used to what the proper amount of water is.

one thing that has helped me is to learn what the weight of the pot feels like when it is soaked vs dry and then depending on the weight i can determine if they need a watering or not.
