Hi all,

I've been playing for about a month now. I switched over to acoustic about a week and a half ago and i've been learning basic chords since the beginning of this week. Before this week I had no issue practicing for an hour or more, but now i notice added sensitivity in my fretting hand, particular my left index finger and can play barely 25-30 minutes. Is this normal? I know calluses take a minute to build up but I thought they would be built by now as I have practiced consistently the past month.

Thanks and any information/advice would help.
