If you use Robert's Rules as your PTO's parliamentary authority, then unless you have bylaws that specifically state that you can use email voting- you can't.
If you are going to go it anyway, set up written procedures as to how you're going to do it and how voting is handled and recorded.
In any case, you would not amend previous minutes. You would put them in the next meeting's minutes as if you are ratifying what was done by email.
