ESP8266 wont send or receive returns busy s . .
What's happening is you are not sending what you think you are, specifically you are not sending the ending return return carriage and newlines properly. 

What you are sending is:

GET /fermControl/update.php?temp=62 HTTP/1.1 \r\n


Besides there being an unnecessary space between the  HTTP/1.1 and return carriage/new line combo the way you are entering it is literal which those characters are not. 

Your serial terminal should send a return carriage/new line combo when you press enter as that is when the ESP8266 knows it has finished receiving a command which from you log it definitely is.

The message above message is also 49 bytes as is not 44 as you specified which doesn't even include the return carriage/new line combo. Your server is waiting for a full HTTP request which includes two return carriage new line pairs which you never send it never gets thus results in the 408 error. This is also why you see the busys... response from the ESP8266 as you are sending more characters then it is expecting and it is telling you it's busy.

You want to send AT+CIPSEND=48 and you want to send this message:

GET /fermControl/update.php?temp=62 HTTP/1.1


Then hit enter twice. This should send the request as desired.
