Hey man I agree with bud that it could be a light issue, but did it all start when you transplanted? I noticed you topped the plant recently. That should help you better distribute the light from the cfls. If your cfls are 5 inches from the top of the plant the bottom of that plant will be getting like 1/6 the light intensity. I hope you really distributed the cfls or you might just grow a lanky plant that mushrooms at the top.
