Ok sorry for the delay...

Here is some pictures from day 17 in flower. I am going to try and get a hold of some mylar to put inside of the grow box. The buds look a little small. I'm thinking that with a generic 400hps and unreflective walls, the plants might not be getting as much light as I would like them to get.

They got their food last night. Some of the fan leaves are turning yellow. Is this something that I should be concerned about?
