Please don't try stretching them after a week. I know this reply is a little late, and I hope it's not too late but my advice would be for you to wait a whole month before trying to stretch again.
You ears most likely tore because it was already stretched out from the 1g stretch and your skin didn't have enough elasticity in them for another stretch right away.
A tear isn't as bad as a blowout, however your ears will never stretch properly unless you give it time to heal. Your sea salt socks and vitamin e oil is a great start. Keep doing that, but wearing silicon plugs will need to stop until your ears are healed. Open wounds and silicon do not mix well, where your ears will begin healing with the silicon material. Which would mean every time you took your plugs out you'll be reopening the wound up.
