Wow! Love your garden. I am really impressed. For yellowing leaves, try adding some nitrogen. I tried growing zucchini in a large walmart trug tub with holes around the bottom and lower sides for drainage--got some squash, but should have only left in one plant instead three--it was just too overcrowded for production. Nitrogen did help the yellowing leaves though. Also, I would go to bigger pots or containers next year for root space. Your garden is very beautiful. 
I would love to share my pics, unfortunately, they are still on my camera. I'm so busy, I haven't had time to off load them to my computer program. I moved to WV from MD last year and haven't had lots of spare time. One of these days . . . .
