Temp too hot at start

I'm printing PLA, and all my prints start at 230 before coming down to 190. This creates a lot of stringy, blobby filament. I can pause at the start so that the extruder has time to get down to temperature, but how do I fix this permanently? I saw another thread mention that this is in the gcode of Octoprint scripts to preheat the extruder to 230, but what do I have to edit to make it not that? The other thread wasn't very specific. Thanks!
