I need a little help...

As you can see in the first picture, the roots can easily be seen when I water. Are the plants rootbound? Or was the water maybe hitting the surface to hard?

Also, some of my buds have browning on the top but I want to keep them as close to the lights as possible so the rest of the plant flowers well...is this a bad idea? Because they seem to be growing into the lights everyday. :thumbsup:

Thanks!
