Wiring review assistance please

I am putting together a version of Kal's and eBrew Supply's 30A, 2 pump, 3 PID system. I wanted to get a little finer control to protect the PIDs so used fuses across it instead of breakers. I don't know if I should bother fusing the SSRs and Contactors, nor which size, but I figured a 5A slow blow would give a measure of protection. If someone wouldn't mind, just double check that I have the right wires to the right poles, and no other silliness in there. Thank you!

IMO you have protection for the elements with the upstream ckt breaker and you need a single 1-2amp fuse for pid power and control signals. If you have pumps you could fuse those also.
