Square Foot Gardening

I'm trying my luck with some Square Foot Gardening (SFG) in my vegetable garden. Unfortunately a fire at my home has limited what I was able to do the past few months. All things considered I am making progress and my vegetable garden is producing. The garden is not as clean as it should be. I built 6 SFG boxes but only planted in 4 of them. Two have very little actually planted but the other 2 are fairly full but not completely. Here's an overall picture.
