ESP8266 with Arduino Uno - Problem with AT+CIPSEND
Your GET is incorrect. You have a CRLF between the GET and the HTTP. It should just be a space.

GET /blah/blah/blah HTTP/1.1\r\nHost: BlahBlah.com\r\n\r\n


Of course the \r\n shouldn't be those specific individual characters, but the ASCII codes 13 and 10 respectively, so printing each line with Serial.println() instead of inserting \r\n might be better.
