First week of no poo--I smell like ACV when I sweat, is this normal?

[Peek-a-boo]

I'm on my first week of no-poo.  I'm noticing that when I sweat during exercise I smell of ACV.  Yuck. :(  Is this normal or am I doing something wrong?

I have hard-ish water, so I'm second guessing whether what I'm experiencing is just normal adjustment or if it's complications from the hard water indicating it won't work.

My hair has been super staticy since about day three of this.
